ACE Appliance HTTP Probe with "POST" query

Does the ACE support HTTP Probe with a "POST" query?
Thanks
Joe

Hi Joe,
The ACE only supports GET and HEAD
Here is the documentation related to this:

ACE match http url with post data

I need to make a layer-7 load balancing decision at the ACE module based on a URL string that includes form POST data. It is important that the balancing decision include and parse the part of the URL after the question mark. This doesn't seem to work with the "match http url" config on the ACE. My interpretation is that the ACE does not consider the POST data to be part of the URL string, and therefore does not include it in the regular expression matching. Am I missing something here, or have I run into a limitation of the ACE module?
class-map type http loadbalance match-any L7__URL_MATCH_CLASS
2 match http url index.php\?field=content.*

Hi
The '?' has a special meaning in the URL. It means the end of the main URL and the beginning of the URL query.
Its not possible to match ? in the url.
One option could be using secondary cookie matching in ACE.
class-map type http loadbalance match-any xyz
2 match http cookie secondary field cookie-value content
Thanks

ACE HTTP Probe with regex

ACE HTTP Probe with regex
Hi,
I'm trying to setup a HTTP probe with expected string rather then a code (config below). I do a GET for the page then a search for a string in the response however it's not working, as probe appears as failed.
I've tested the connection to the server by using telneting and then looking at the page displayed to make sure the string I want to match is in the response.
probe http HTTP-PROBE
port 43050
interval 30
passdetect interval 30
passdetect count 1
request method get url /action=help
open 43050
expect regex action=help
Q. Is there anything wrong with this configuration and what I'm trying to achive?
Thanks,
Pritesh

Use "expect status" under probe config. expect regex doesnt work if expect status is not configured.
expect regex work flawlessly with static pages. It doesnt work all the time with dynamic pages.
Specially if "content-length" header is missing from Server response.
Hope it helps

ACE Module - HTTP Probe failure

Hi,
I have configured the http probe with expect status 200 202, but the probe fails despite availability of the port on rserver.
I tried head/get method to see the return code, and it came back with HTTP1.1/302. How can I configure an http probe to understand HTTP 302 code as success return.
Thanks.

I changed the expect status value as below
probe http TEST-HTTP
interval 30
passdetect interval 10
request method head
expect status 302 302
The probe is still failing with the log message

CSM HTTP Probes with Method GET

Hello.
How does the HTTP Probe with Method GET work on CSM and what is the difference with CSS?
CSS calculates the HASH of the web page it receives as a first answer and considers that as a REFERENCE HASH, to compare with subsequent answers. Is the behaviour of the CSM the same?
In the CSS it is also possible to insert the HASH in the configuration as a reference HASH. I did not find such a command on the CSM. Is that feature not present on CSM?
Thanks.

the CSM just looks for the response code.
No hash or anything similar to the CSS.

Gilles.

ACE 4710 HTTP Probes

Using the ACE 4710 for loadbalancing a Sharepoint site.
We currently have a HTTP probe setup to check the port 80 status of the rserver.
Is there anyway to get the HTTP probe to check a DNS entry for each of the application sites? For instance http://info vs http://site are two different web sites running on the same IP. One site could have a problem but the actual port 80 for the IP may be still alive.
Thanks for any information.

Has anyone figure this out? I am tring to get healthchecks/probes setup in this same fashion. I have 2 servers with 1 IP but have many sites. I want to probe each side and ensure I get a 200 code. I also have to provide credentials to the site. It seems that if i open IE I can log in just fine to the site with the credentials. However there is an active x control box that is wanting to be installed. When I set this up on my ACE it seems I am getting a http 401 unauthorized error. I have done a wireshark capture while I was browsing and I see the 401 however it also reports a 200 code after that. Do you think this is a problem because of the active x control wanting to be downloaded? Or is this an issue with the first http code that is recieved by the probe, that being the 401 and then the 200? Below is my config (cleaned of course).

Strange HTTP probe with .cfm files.

Hey All,
I setup an http probe that checks a .cfm page for a keyword. according to the documentation there needs to be a content-length in the header for this to be parsed correctly. For some reason this .cfm page does not send the content-length. The developer manually told coldfusion to put the content-length in the header and I can see that the header now has the content-length. The probe is still failing with "Unrecognized or invalid response" If i put a test html page with a keyword, it parses it correctly and passes. If i change the keyword it fails as expected. Has anyone had any issues with the headers of coldfusion? There is no compression on the server side. Below is the probe.
probe http KEYWORD
interval 15
passdetect interval 30
request method get url /index.cfm
open 2
expect regex "go"
Any help or suggestion would be much appreciated.
Regards,
Christian

Hey Christian and Paul,
Actually, when using expect regex, you don't need the expect status. I alerted the documentation team about this and they have updated the documents with the following note:
Note If you do not configure an expected status code, any response from the server is marked as failed. However, if you configure the expect regex command without configuring a status code, the probe will pass if the regular expression response string is present.
Christian,
You mention that you see the error message Unrecognized or invalid response, even with the content-length header added. Is this the same error message you got before your app team added the header? If so, then I might suspect that the ACE doesn't like the format they used. The header should look like this:
Content-Length:
This is per RFC2616 and can be found at section 14.13 here. Note that the C and the L are uppercase, the header name is immediately followed by a colon, and there is a spece between the colon and the value.
I would recommend confirming that the header matches this description in a network capture. If it does match, then I would like to see the capture, if possible.
Thanks and I hope this helps,
Sean

Problem with post query trigger

Hi,
I have a multi record block and there is a post-query trigger on it. Based on values of this block I populate other values over the other control block.
I wrote code in post-query trigger and when I execute the query and go to last but one record. The values in the control block are from last record instead of last but one record. Pls help me to fix
Thanks,

if you want to see the data in the control block synchronized with the database block then use the WHEN-NEW-RECORD-INSTANCE and not the POST-QUERY.
with the POQ you add additional data (in non-basetable-items) to the records in the database block

ACE 4710 http probe get url question

I am trying to create a http probe using the request method get url command. My url contains a question mark and the ACE will not accept the url as is and it strips out the question mark character. Is there a way to make the ace accept a url containg a question mark?
probe http HTTP_PROBE
port 9040
interval 10
faildetect 5
passdetect interval 60
expect status 200 200
open 1
The url I am trying to enter is /psp/epprod/?cmd=login
When I enter it the ACE does as shown below
(config-probe-http)# request method get url /psp/epprod/?
<LINE>
ACE-APP-02/vc_peoplesoft(config-probe-http)# request method get url /psp/epprod/cmd=login
It strips out the ? character.

Hi Nicholas,
To enter a question mark you need to type ctrl+v prior to entering the ?
You enter the control key then lowercase v, then your question mark.

Local Director http probes with URLs and http redirect mode

I am trying to configure http probes on my Local director 430 running 4.2.3
I am using http redirect mode so the Virtual is bound to URLs not REALs with are linked to DIPs which are bound to REALs. So far the probes seem to not actually do anything. Does anyone know if the probes are compatible with URL redirect loadbalancing. And if so how one would go about configuring it.
Thanks for your help.

keepalive can be used for the probe notification in this case.
Check the following url for details.

Can somebody plz. look at it & help to fix it?
Zulfi.

The way you have it coded now, the user will always be authenticated; the "Login Failed") logic will never happen. There is always a recordset returned from a query (unless an exception is thrown). The recordset may contain 0 or more records. The cursor position in a record set starts before the potential first record. The next() method will return true if there is a first row (or a next record) and false if you are at the end of the recordset. You may want to try the code like this (With the html ommitied for readability):
- Chris
new code
Statement statement =con.createStatement();
ResultSet rs=statement.executeQuery("select * from Login where
userid="+ userid + "and passwd="+passwd);
if(rs.next()==false)
// Login failed code
else
// Successfull logon code
conn.close();
Old Code
Statement statement =con.createStatement();
ResultSet rs=statement.executeQuery("select * from Login where userid="+ userid + "and passwd="+passwd);
if(rs==null) {
out.println("Enters herer");
%>
<H1> Login Failed!</H1><BR><HR><BR><P><BR>
Your Userid & Passwd were invalid. <BR>

Accessing Java webservice (XML over http) via WCF or HTTP adapter with content-type and authorization HTTP headers with POST method

Hi Team,
I need to access Java web service which is simple service and accepts and returns XML over HTTP. No credentials are needed to access the service. We need to pass following two HTTP headers (Content-Type and Authorization) along with XML request message:
<GetStatus> message is being constructed in the orchestration and URI is constant to access.
Which adapter shall I use to get the response back? I tried using WCF-WSHttp with Security Mode = Transport, and different options of client credential types but every time, error returned stating:
System.Net.WebException:
The HTTP request is unauthorized with client authentication scheme 'Basic'. The
authentication header received from the server was 'Basic realm='.
Authentication failed for principal Basic. Message payload is of type:
String
In Fiddler, request looks line following
POST <https://URL/GetServiceReopnse HTTP/1.1
Content-Type: application/xml
Authorization: Basic cmVmU3RhdHN2Y19kgeRfsdfs=
Host: <Server name>
<GetStatus XMLNS="http://server.com/.....">
<OrgId>232323</OrgId>
<HubId>3232342323</HubId>
</GetStatus>
MMK-007

First, you should not use the HTTP Adapter because it's been deprecated and replaced by WCF.
Start with the WCF-Custom Adapter and select the customBinding.
You should start with the textMessageEncoder and httpTransport and go from there.

Weird prob with sub query

Plz help prob with a query and.. a trigger

hi..
1)i've created a view.gave the commit..
now when i execute this query i get no rows selected...
sql>select text from user_views where view_name='d1_v';even when i give sql>select * from user_views; all i see are column names and nothing else..
do i need to grant my user any privilige. my user has create any view privilige.
2)
is it possible for me to create a trigger that updates records by itself for every 6 months by adding 1000 to the sal field
i tried
create or replace trigger after logon on emp ..............like that
but i receive an error saying system triggers cannot be based on tables or views..
plz help me out..
thank u
rajiv

1. Try "select text from user_views where view_name='D1_V';
BTW, no need to use "commit", CREATE VIEW is a DDL command, and DDLs do implicit commit.
2. Why do you want to use triggers ? You can do that in at least two other ways : cron jobs and Oracle jobs.

Cisco ACE Mod 30 - HTTPS probes are failing after hardware replacement.

We recently had a hardware failure on ACE Mod30. The replacement went in relatively painless (except for having to import about 100 SSL Certificates and Private Keys).
However, on the new ACE, the HTTPS probes are failing for all contexts using them. We can work around this by using TCP-443 probe, but the customer prefers that we actually request a logon page to ensure that the application is running properly.

Hi,
For HTTS Probes to be successful, you don't need to have SSL Certs/Private keys on ACE, unless servers are doing client authentication. When ACE sends HTTS Probes to servers, it acts as a client.
Here are few things that can be tried:
- Test HTTS probe with only one server. Reload the server to clear any SSL cache on it.
- check SSL probe detail to verify the error code received
- Take captures between ACE and that server to find at what stage of the probe packet exchange flow is failing.
Here is a good link to troubleshoot HTTPS probe issues:
