Hi,
Can we use regular expression in configuration/deployment plan while searching for specific text in composite.xml?
Thanks

While on vacation, I bought an Airport Express in Slovenia, planning to use it in my Moscow apartment. I plugged everything in, seem to have followed the directions properly for configuration - except for one thing. Moscow does not come up as an option for location. So I tried ticking Ljubljana (Slovenia) as location (since that's where I bought it). The cycle seemed to have worked, I got a green light on the Airport Express, but the network didn't work. I tried going in to change the location, and chose something called Universal, but the network still didn't work.
Is the fact that Moscow doesn't come up among the options going to be a problem? Or is it possible I am doing something else wrong?
Anyone have any insights?AirPort Utility for the iPhone, iPad, etc does not support the older version of the AirPort Express that you have.
Try installing AirPort Utility on the Lenovo laptop to see if you can configure the AirPort Express that way.
If the laptop runs XP SP3 or Vista SP2.....use AirPort Utility 5.5.3 for Windows - Support - Apple
Windows 7....use AirPort Utility 5.6.1 for Windows 7 - Support - Apple
Remember that the SB5101 modem must be fully reset before it will associate correctly with the AirPort Express. That means pressing the reset button on the back of the modem (if present) and powering off the modem for at least 30 minutes, then connecting it to the AirPort. -
Regular Expression and jUnit in ADF Mobile
Hi Guys,
I tried to implement Regular Expression in ADF Mobile, but in my jUnit that I was configured to unit test purpose in my application.
Shown error below inside jUnit plane.
java.lang.NoClassDefFoundError: oracle/adfmf/util/regex/Pattern
How to solve this issue for jUnit ?I'll start by answering your Q2 - while in theory you can use the same application for both accessing from a browser on a pc and on a phone - in reality the user experience on the phone is not going to be good because of the limitation of the screen size. Users will need to constantly zoom-in scroll around etc. This is why many people who target application for smart phones prefer to build a separate UI for the mobile device.
Now question 4 which relates to 1 - We haven't tested the ADF Faces components on the browser of blackberry and so there is a chance that some of their functionality won't work there. We did test and certify the ADF Faces components with the safari mobile browser (iOS) - so this is why you see them work there better.
This is why we recommend that if you are targeting a blackberry (and other mobile devices) you'll use the Trinidad set of components and in general ADF Mobile Browser project type.
(see example here: https://blogs.oracle.com/shay/entry/building_iphone_interfaces_for_oracle ). This also means that you'll have the check box checked for mobile device when you create a JSF page.
For question 3 - when the next ADF Mobile solution will be released you'll be able to create applications that install on the device itself. -
URL paths and regular expressions in ASDM
Some background info - I've recently switched to an ASA 5510 on 8.4(3) coming from a Checkpoint NGX platform (let's say fairly quickly and without much warning ). I have a couple questions and they're kind of similar so I'll post them up. I've read docs about regex and creating them both via command line and ASDM, but the examples always seem to include info I don't need or honestly something I don't understand yet (mainly related to defining class\inspect maps). If someone could provide a simple example of how to do these in ASDM that would help a lot in understanding how regular expressions are properly configured. So here we go.
I know this is basic but I need to make sure I understand this properly - I have a single web server (so this won't be a global policy) where I need to allow access to a specific URL path\file and that's it. So we'll call it \test\testfile.doc. Any other access to any other path should be dropped. What's the best way to do this in ASDM (6.4)? I think if I saw a basic example for this I could figure out next few questions but I'll post them as well just in case.
I have another single public web server (again this won't be a global policy) where I'd like to specify blocking file types, like .php, .exe., etc... again a basic example would be great.
Lastly, and this is kind of related, but we have a single office/domain and sometimes we get spam from forged addresses appearing to be from our domain. On Checkpoint I used to use its built-in SMTP security server and could define if it received mail from *@mydomain.com to drop it because we would never receive mail externally from our own domain name. I saw something similar with ESMTP in ASDM and it looks kind of like how you set up the URL access mentioned above. Can I configure this in ASDM as well, and if so how?
TIA for your help,
Jordan/bump

Namburi,
When you said you used the Reg Exp tool, did you use it only as
preconfigured by the iMT migrate application wizard?
Because the default configuration of the regular expression tool will only
target the files in your ND project directories. If you wish to target
classes outside of the normal directory scope, you have to either modify the
"Source Directory" property OR create another instance of the regular
expression tool. See the "Tool" menu in the iMT to create additional tool
instances which can each be configured to target different sets of files
using different sets of rules.
Usually, I utilize 3 different sets of rules files on a given migration:
spider2jato.xml
these are the generic conversion rules (but includes the optimized rules for
ViewBean and Model based code, i.e. these rules do not utilize the
RequestManager since it is not needed for code running inside the ViewBean
or Model classes)
I run these rules against all files.
See the file download section of this forum for periodic updates to these
rules.
nonProjectFileRules.xml
these include rules that add the necessary
RequestManager.getRequestContext(). etc prefixes to many of the common
calls.
I run these rules against user module and any other classes that do not are
not ModuleServlet, ContainerView, or Model classes.
appXRules.xml
these rules include application specific changes that I discover while
working on the project. A common thing here is changing import statements
(since the migration tool moves ND project code into different jato
packaging structure, you sometime need to adjust imports in non-project
classes that previously imported ND project specific packages)
So you see, you are not limited to one set of rules at all. Just be careful
to keep track of your backups (the regexp tool provides several options in
its Expert Properties related to back up strategies).

This is a great input for our migration. Though we used the existing
Regular Expression Mapping tool, we did not change this to meet our
own needs as mentioned by Mike.
We would certainly incorporate this to ease our migration.

Great response. By the way, the Regular Expression Tool uses thePerl5 RE
syntax as implemented by Apache OROMatcher. If you're doing lotsof these
sorts of migration changes manually, you should definitely buy theO'Reilly
book "Mastering Regular Expressions" and generate some rules toautomate the
conversion. Although they are definitely confusing at first,regular
expressions are fairly easy to understand with some documentation,and are
superbly effective at tackling this kind of migration task.

Also, (and Matt's document may mention this)
Please bear in mind that this statement is not totally correct:
Since the migration tool does not do much of conversion for
these
utilities we have to do manually.Remember, the iMT is a SUITE of tools. There is the extractiontool, and
the translation tool, and the regular expression tool, and severalother
smaller tools (like the jar and compilation tools). It is correctto state
that the extraction and translation tools only significantlyconvert the
primary ND project objects (the pages, the data objects, and theproject
classes). The extraction and translation tools do minimumtranslation of the
User Module objects (i.e. they repackage the user module classes inthe new
jato module packages). It is correct that for all other utilityclasses
which are not formally part of the ND project, the extraction and
translation tools do not perform any migration.
However, the regular expression tool can "migrate" any arbitrary
file
(utility classes etc) to the degree that the regular expressionrules
correlate to the code present in the arbitrary file. So first andforemost,
if you have alot of spider code in your non-project classes youshould
consider using the regular expression tool and if warranted adding
additional rules to reduce the amount of manual adjustments thatneed to be
made. I can stress this enough. We can even help you write theregular
expression rules if you simply identify the code pattern you wish to
convert. Just because there is not already a regular expressionrule to
match your need does not mean it can't be written. We have notnearly
exhausted the possibilities.
For example if you say, we need to convert
CSpider.getDataObject("X");
To
RequestManager.getRequestContext().getModelManager().getModel(XModel.class);
Maybe we or somebody else in the list can help write that regularexpression if it has not already been written. For instance in thelast
updated spider2jato.xml file there is already aCSpider.getCommonPage("X")
rule:
<!--getPage to getViewBean-->
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getViewBean($1ViewBean.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
Following this example a getDataObject to getModel would look
like this:
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getModel($1Model.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
In fact, one migration developer already wrote that rule andsubmitted it
for inclusion in the basic set. I will post another upgrade to thebasic
regular expression rule set, look for a "file uploaded" posting.Also,
please consider contributing any additional generic rules that youhave
written for inclusion in the basic set.
Please not, that in some cases (Utility classes in particular)
the rule
application may be more effective as TWO sequention rules ratherthan one
monolithic rule. Again using the example above, it will convert
CSpider.getDataObject("Foo");
To
getModel(FooModel.class);
Now that is the most effective conversion for that code if that
code is in
a page or data object class file. But if that code is in a Utilityclass you
really want:
>
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
So to go from
getModel(FooModel.class);
To
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
You would apply a second rule AND you would ONLY run this rule
against
your utility classes so that you would not otherwise affect yourViewBean
and Model classes which are completely fine with the simplegetModel call.
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[getModel\(]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[getModel\(]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getRequestContext().getModelManager().getModel(]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
A similer rule can be applied to getSession and other CSpider APIcalls.
For instance here is the rule for converting getSession calls toleverage
the RequestManager.
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[getSession\(\)\.]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[getSession\(\)\.]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getSession().]]>
</mapping-rule-substitute>
</mapping-rule-replacement>

I will post a document to the group site this evening which has

on various tactics of migrating these type of utilities.
Essentially,
you
either need to convert these utilities to Models themselves or
keep the
utilities as is and simply use the

to statically access Models.
For CSpSelect.executeImmediate() I have an example of customhelper

Subject: [iPlanet-JATO] Use Of models in utility classes
Hi All,
In the present ND project we have lots of utility classes.
These
classes in diffrent directory. Not part of nd pages.
In these classes we access the dataobjects and do themanipulations.
So we access dataobjects directly like
CSpider.getDataObject("do....");
and then execute it.
Since the migration tool does not do much of conversion forthese
utilities we have to do manually.
My question is Can we access the the models in the postmigration
sameway or do we need requestContext?
We have lots of utility classes which are DataObjectintensive. Can
someone suggest a better way to migrate this kind of code.

Could you try being a bit more specific?
Firstly, i am sorry i didn't post the output. I should have know better.
Secondly, chill out.
I have used above regex with grep command. Output from terminal is:
zsh: bad pattern: ^[^#]
In bash it works perfectly.
If i issue "setopt re_match_pcre" i have the same ouput as above.
EDIT: If i issue "unsetopt no_match" it actually works but i have to change the regex from "\^\[^#]" to "\^[^#]" otherwise i get the same output as above. In bash both options work.

Hello All,
I come from Perl scripting language background. Perl's regular expressions are rock solid, robust and very fast.
Now I am planning to master Regular Expressions in Oracle.
Could someone please point the correct place to start with it like official Oracle documentation on Regular Expressions, any good book on Regex or may be any online link etc.
Cheers,
Parag
Edited by: Parag Kalra on Dec 19, 2009 11:03 AMHi, Parag,
Look under [R in the index of the SQL language manual|http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/index.htm#R]. All the regular expression functions and operators start with "REGEXP", and there are a couple of entries under "regular expressions".
That applies to the Oracle 11 and 10.2 documentation. Regular expressions were hidden in the Oracle 10.1 SQL Language manual; you had to look up some similar function (like REGR_SYY, itself hidden under S for "SQL Functions", and then step through the pages one at a time.
Sorry, I don't know a good tutorial or introduction.
If you find something hopeful, please post a reference here. I think a lot of people would be interrested. -
Regular expressions in ActionScript??
I have been looking at the Adobe publication Programming Action Script (pdf) and it
specifies ECMA-262 3rd edition specification. But the specification don't seem to
state exactly what type of regular expression engine and version is used.
Is it POSIX, or PERL compatible regular expressions (or both)?
I have read and used the classic O'Reilly text Mastering Regular Expressions
and coded regular expressions in javascript/php/etc (anywhere regular expressions
could be use, Apache configuration file, other server config files, etc etc etc)
There is a difference in the type of engine used, where as performance is
concerned, as well as the range of syntax valid in a particular implementation.
Thank You

Trying to use regular expressions to convert names to Title Case
I'm trying to change names to their proper case for most common names in North America (esp. the U.S.).
Some examples are in the comments of the included code below.
My problem is that *retName = retName.replaceAll("( [^ ])([^ ]+)", "$1".toUpperCase() + "$2");* does not work as I expect. It seems that the toUpperCase method call does not actually do anything to the identified group.
Everything else works as I expect.
I'm hoping that I do not have to iterate through each character of the string, upshifting the characters that follow spaces.
Any help from you RegEx experts will be appreciated.

* ROY BLOUNT, JR. --> Roy Blount, Jr.
* CAROL mosely-BrAuN --> Carol Mosely-Braun
* Tom Jones --> Tom Jones
* ST.LOUIS --> St. Louis
* ST.LOUIS, MO --> St. Louis, Mo <-- Avoid City Names plus State Codes
* This is a work in progress that will need to be updated as new exceptions are found.
public static String toNameCase(String name) {
* Basic plan:
* 1. Strategically create double spaces in front of characters to be capitalized
* 2. Capitalize characters with preceding spaces
* 3. Remove double spaces.
// Make the string all lower case
String retName = name.trim().toLowerCase();
// Collapse strings of spaces to single spaces
retName = retName.replaceAll("[ ]+", " ");
// "mc" names
retName = retName.replaceAll("( mc)", " $1");
// Ensure there is one space after periods and commas
retName = retName.replaceAll("(\\.|,)([^ ])", "$1 $2");
// Add 2 spaces after periods, commas, hyphens and apostrophes
retName = retName.replaceAll("(\\.|,|-|')", "$1 ");
// Add a double space to the front of the string
retName = " " + retName;

Edited by: FuzzyBunnyFeet on Jan 17, 2011 10:57 AMHopefully someone will still be able to provide a RegEx solution, but until that time here is a working method.
Also, if people have suggestions of other rules for letter capitalization in names, I am interested in those too.

Converting String Characters into Regular Expression Automatically?
Hi guys.... is there any program or sample coding which is available to convert string characters into regular expression automatically when the program is run?
Example:
String Character Input: fnffffffffffnnnnnnnnnffffffnnfnnnnnnnnnfnnfnfnfffnfnfnfnfnfnnnnd
When the program runs, it automatically convert into this :
Regular Expression Output: f*dhey guys.... i am sorry for not providing all the information that you guys need as i was rushing off to urgent meeting... for my string characters i only have a to n.. all these characters are collected from sensors and stored inside database... from many demos i have done... i found out that every demo has different strings of characters collected and these string of characters will not match with the regular expressions that i had created due to several unwanted inputs and stuff... i have a lot of different types of plan activities and therefore a lot of regular expressions.... if i put [a-z|0-9]*... it will capture all characters but in the same time it will be showing 1 plan only.... therefore, i am finding ways to get the strings i collected and let it form into regular expression by themselves in the program so that it will appear as different plans as output with comparing with the regular expression that i had created.... is there any way to do so?
please post again if there is any questions u are still not familiar with... thank you... -
BUG?? Syntax Highlighting Regular Expressions
I'm working on a rather long regular expression in
dreamweaver code view. It has about 200+ characters in it.
I wrote it in another application and copied it over for use
in js, and it wouldn't highlight correctly (sort of like when you
leave off quote on a string). Naturally I thought I screwed up my
regexp or forgot to escape a character or something so I went
through it re-writing it and checking everything but it was
correct. I saved the page and ran it in the browser and sure enough
it worked.
So I started typing the regexp from scratch this time in
dreamweaver to see when it stopped highlighting correctly. It
stopped at exactly 100 characters including opening and closing
forward slashes. I tried writing another exp this time filled with
just one letter. Again 100 characters exactly - not one more.
Example:
var reg1 =
/ssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss ssssssssss/
var reg2 =
/ssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss sssssssssss/
reg1 will highlight correctly, while reg2 won't.
Is this a bug or am I missing something? The highlight rule
(in Configuration\CodeColoring\CodeColoring.xml) is
(\s*/\e*\\/
-or-
=\s*/ \e*\\ /
There seems to be no limitation to length there.
While this is not a huge deal, I might as was well be coding
in notepad (or my other script editors which highlight this
correctly) because the highlighting is worthless from this point
on.
I could make these strings instead of literals but I have a
lot of these long expressions and would rather not go through them
and escape all of my back slashes (there are tons) as well as
quotes - and make them more un-maintainable as they already are.
Anyone have this problem? Or a solution to it?random_acts wrote:

I have never written a regex as long as that, but was
fascinated by your
question, so attempted to replicate your problem.
I gave up at 614 characters, but the syntax coloring didn't.
I suggest
that you submit a bug report with the details of your actual
code:

Juniper MX Regular expressions and user permissions ACS 5.4
Hi everyone!
Im having some trouble with regular expressions and permissions on our Juniper MX routers through ACS 5.4, and i would like some insight/help/poitners!!
We have a team of engineers that should only have read only permissions (important: show configuration) and also be able to just change the description on interfaces.
Thus far with the following regular expressions set for the shell profile they are going through i have managed the above, however the problem is when an engineer inputs "Show configuration", only the interfaces descriptions configuration is shown! The rest of the configuration will not be printed.
deny-commands1=.*.
allow-commands1=configure
deny-configuration1=.*.
allow-commands2=interfaces .*. description .*$
allow-configuration1=interfaces .*. description .*$
allow-commands2=show configuration.*
allow-commands3=show configuration
(some of these regex i know that are not needed, i was just playing around to check everything before posting)
Any pointers as to why or how to resolve this?
example output with the above:
show configuration

SpyrosYou are absolutely right!! I was doing research online after posting the above. The correct RADIUS attribute to use is actually CVPN3000/ASA/PIX7.x-Group-Based-Address-Pools. Then create the pool in ASA, and call that pool's name in ACS under that RADIUS attribute. Someone explained this perfectly in this community before. Much appreciate your answer!
Here's from another post last year:
ACS 5 does not have the feature of IP pools. Logically its always good to setup pools locally on vpn server and if you want user to pick ip from specific local pool you can configure acs to push that attribute.
On ACS Go to > Policy Elements -> Network Access -> Authorization Profiles -> Create ->
Name of the Policy ->Dictionary Type: Radius-Cisco VPN 3000/ASA/PIX7.x
Attribute Type : CVPN3000/ASA/PIX7.x-Group-Based-Address-Pools
Attribute Type: String
Attribute Value : Static MYPOOL (Name of the Pool which is defined on the ASA)

Getting "Inner Html" using Regular Expressions. Learning RE in SDK1.4.
Hello group.
I am learning Regular Expressions in JAVA SDK 1.4 first. Not PERL or other language.
Using the utility at the following link I am trying to get all the text between the <TR> and </TR> tags.
http://jakarta.apache.org/oro/demo.html
This seems simple but the line returns, breaks etc.. make it more difficult. I have worked on this for hours.
There will be multiple table rows in my stream.
My goal is to first get the text between the <TR> Tags...
Then I was going to use groups to get data0, data1, data2, data3.
Does this sound like a good plan? Should I use multiple RE or one RE that does 4 group returns.
I was thinking the applet was causing my problem.
<TR>.*?</TR> does not work.
(<tr>\s*([^(</tr>)])+</tr>) does not work.
I can get data0 to work as well as data1,2,3.
Would it make more sense to split this multiple row table by </tr>?
One row of malformed html (actually multiple rows):
<TR>
<TD bgColor=#ffffff><A class=fav
href="http://nicesite.com/data0"
>nicesite</A><IMG
src="smile.gif"></TD>
<TD bgColor=#12ff22><SPAN class=fav>data1</SPAN></TD>
<TD bgColor=#12ff22><SPAN class=fav>data2</SPAN></TD>
<TD bgColor=#12ff22><SPAN class=fav>data3</SPAN></TD>
<TD align=middle bgColor=#ffffff><A
href="#"><IMG
src="smile.gif" border=0></A></TD>
<TD align=middle bgColor=#ffffff>data
4</TD>
<TD align=middle bgColor=#ffffff>data5</TD></TR>

make it more difficult. Yes, they do indeed
There will be multiple table rows in my stream.

Tags...
Then I was going to use groups to get data0, data1,
data2, data3.
Does this sound like a good plan? Should I use
multiple RE or one RE that does 4 group returns.One of the main features of regexes that you must realize
is that they are mainly suited for non-recursive, linear data structures
(btw, that's why regexes in general are hardly suited for html).
So, if the number of TD items is fixed, you could
1. search using a single pattern for the whole row, something like
"<PatternForTR>"+
"<PatternForTD>(<PatternForData>)<PatternFor/TD>"+
"<PatternForTD>(<PatternForData>)<PatternFor/TD>"+
"<PatternFor/TR>"
so the group1 would contain data1 and so on
Otherwise, you should
2. find each row using
"<PatternForTR>(.*?)<PatternFor/TR>",
then search the contents of group1 using the
"<PatternForTD>(<PatternForData>)<PatternFor/TD>".
>
<TR>.*?</TR> does not work.The pattern itself is ok, but in order for it to work one should enable the DOTALL flag (the 's' flag in jregex demo), as the '.' doesn't accept line breaks by default.
(<tr>\s*([^(</tr>)])+</tr>) does not work.It seems that [^(</tr>)]+ actually is a nonsense in this context.
It describes a string that consists of any chars but '(', ')', '<', '>', 'r', 't', '/'.
What you actully meant (a string that doesn't contain "</tr>")
is just achieved by using non-greedy quantifier in <TR>.*?</TR>.
>
I can get data0 to work as well as data1,2,3.
Would it make more sense to split this multiple row
table by </tr>?Going the second way above, you could find rows using the
general pattern for TR:
<tr.*?>(.+?)</tr> and search their contents(i.e. the group#1) using the
general pattern for TD
<td.*?>(.+?)</td> Finally, this is the specific pattern for TD that doesn't include the leading
and trailing tags into group1:
<td[^>]*>(?:\s*</?[^>]*>)*\s*(.+?)(?:\s*</?[^>]*>)*\s*</td>It succeded in finding

FM9 SDL Authoring Assitant Regular Expression Syntax?
I'm trying to trick SDL into identifying words that are not approved by STE.
Under "Configure|Style and Linguistic Checks|User Defined Rules" the program allows regular expressions to create custom rules.
I have all other options in the Utility unchecked.
I am by no means a pro at regular expressions but was able to create a pretty solid command at http://regexlib.com/RETester.aspx.
The idea is to create an expression that looks for any word other than those seperated by vertical bars.
For the test text "this is not the way that should work. this is not the way that should work."
\b(?:(?!should|not|way|this|is|that).)+
returns: the work the work
At that website, I can change the excluded words and it works every time. Change the test text, same thing, still works.
Perfect! I ripped every approved word in STE into the formula and it (SDL) only returns words at the end of the sentence that are followed by a periods and question marks. So I added"\." to the exclusion list in the expression and it only found words next to question marks. I excluded question marks and now it finds nothing. I don't understand this as I wasn't aware that I had any criteria in the expression that dictates functionality only at the end of the sentence.
I have an O'reilly book to refer to, if anyone can give me a shove in the right direction as to which set of rules to adhere to, I would appreciate it. Why did negative word matching have to be my introduction to this subject?I tried your expression in a couple of regex tools and it seems to parse as you wanted it to. I suspect that the SDL implementation doesn't follow the unix/linux standards. I haven't used the tool and the usage documentation is non-existant, except for the limited flash-based demo.
From the SDL knowledgebase, it states that their regex filter uses the .NET regex flavour and I believe that the differences on this are explained in the "Mastering Regular Expressions" book. -
ACE20 Module, webservices and regular expressions.
Hello All,
I am trying to loadbalance requests for webservices in a serverfarm. But for some reason, ACE20 module y not making matches on the requests.
We have a serverfarm Prod1 with 2 real servers and another serverfarm named WSDL with other 2 real servers.
The idea is the following, if we receive the following string, /App.WebService, the ACE should redirect it to serverfarm Prod1, but if it receives /App.WebService?wsdl, it should be redirected to WSDL.
Request with string /App.WebService --------------> ServerFarm Prod1
Request with string /App.WebService?wsdl -----> ServerFarm WSDL
We use regular expression in L7 class maps to make the loadbalance to happen.
class-map type http loadbalance match-all APP.WEBSERVICES-L7-SLB
2 match http url /App\.WebService\?wsdl
class-map type http loadbalance match-all APP-L7-SLB
2 match http url /App\.WebService
policy-map type loadbalance first-match L7_SLB-POLICY
class APP.WEBSERVICES-L7-SLB
serverfarm WSDL
class APP-L7-SLB
serverfarm Prod1
class L4_SLB_DATAPOWER(9050)
loadbalance vip inservice
loadbalance policy L7_SLB-POLICY
loadbalance vip icmp-reply
appl-parameter http advanced-options HTTP_PARAM
ssl-proxy server wildcard.test.org
connection advanced-options TCP_PARAM
But the ACE20 Module seems to be removing the ?wsdl from the URL and only the class-map called APP-L7-SLB is being matched.
Any comments or suggestions on why this could be happening?
Thanks in advance,
FernandoHello Kanwal and all,
Finally, after reading and reading I found a fix to this problem. Seems that the HTTP protocol uses the question mark (?) character as a delimiter for data appended to the URL. So, if you get the following:
www.test1.org/App.WebService?wsdl
If you configured a L7 class map to parse the URL, it will only parse until the question mark (?).
So you need to create a PARAMETER-MAP changing the URL delimiter start. Here is an example:
parameter-map type http HTTP_PARAMETER_MAP_WSDL
persistence-rebalance strict
set secondary-cookie-delimiters ;!@?
set secondary-cookie-start ;
I used the semicolon ( ; ) as delimiter.
Hope this helps.
Fernando
