JavaScript URL rewritting and screen blinking

Hi Experts,
I am working with EP and JavaScripts. We are making changes through JavaScript in Portal.
I have to rewrite the URL's with new URL's by using JavaScript. I am using the following code-
if( parent.document.body.innerHTMLindexOf(URL)>0)
rewriteLinks(sourceURL,targetURL);
if( parent.document.body.innerHTMLindexOf(URL)>0)
rewriteLinks(sourceURL,targetURL);
f( parent.document.body.innerHTMLindexOf(URL)>0)
rewriteLinks(sourceURL,targetURL);
But, the problem is screen is blinking for 3 times to execute the above 3 if()conditions. I think, for every if() the screen is reloading.
How to stop reloading for every if() condition? Once all the if() conditions executed, then only reload the screen.
Regards,
Vijay.

Hi Vijay,
It sholun't happen in javascript.U have put 3 conditions same as per the code u send.Check that once.
Any u can stop blinking in javascript.Refer this.

Cookies, URL-Rewriting, and Sessions

Hi All,
I am aware that this is probably a question that has been asked many times in the past. Nonetheless, I have not been able to fully comprehend the differences. Therefore I would appreciate it, if someone could kindly spend some time explaining the differences between the three and when each would be the most preferred solution. ( cookies, url rewriting and sessions )
So far what I understand is that, cookies can be used to store small amounts of data not more than 4kb, and that most browsers can not accept more than 20 at a time.... but would it be correct to say that the data is stored within the http headers ?
URL rewriting, on the other hand is a method which can be used if cookies have been disabled by a browser. The 'session id' is appended to the url, and used to remember the data. ( how ? ). Although, it does mean that the programmer has to be very careful and ensure that rewriting occurs everytime it is passed to the browser, including redirection. ( whatever that means ? )
Http sessions, seem to be the best solution out of the three ( but if this is the case, why are cookies and rewriting still hanging around today ? And even being taught at universities ? ). Also, they work on top of cookies and if these have been disabled sessions will not work !! ....
As you can see ( from the above ) I do not have a thorough understanding of the three methods, especially if it comes to specifying the differences between the three.
I would appreciate an explanation.

HttpSessions use cookies or url rewritting to pass the session id which the server uses to associate a particular session with a particular request. A well developed web application will be written to use url rewriting when a client has cookies disabled. That being said I yet to see such a web application and personally believe that few people still disable cookies.
Cookies still have uses.
Persistant cookies are used to store data that needs to persist between sessions. This data is stored by the browser in a text files and passed to the server in the header. An example of this would be a site that offers personalization would store the user's id so that each time the user accesses the site he would see his personalization without being required to log in. Yahoo is a good example.
In memory cookies are stored in the browser's memory and is used to store temporary data that goes away when the browser closes. Again this data gets passed to the server in the headers. Temporary cookies can be used to pass data between seperate web applications runing on the same host where storing the data in the session will not because each application has it's own session.

Sessions, URL Rewriting, and Cookies

First some background, then some questions:
          BACKGROUND
          I have written an application framework to use with JSP/EJB/Servlet
          based applications. This framework does URL rewriting
          (response.encodeUrl) for all URLs generated by the application, and I
          have URL-based session support turned on in WebLogic.
          Despite the fact that my browser is set to support cookies on my test
          machines, I have noticed that intermittently the URL rewriting to
          support session IDs kicks in. Then, later, it goes away again. This
          would seem to indicate that the client browsers are (for no apparent
          reason) deciding to occasionally not support sessions with cookies, so
          that the server has to step in and do URL writing instead.
          QUESTIONS
          1. Has this sort of behavior been reported by anyone else?
          2. Is there a servlet/JSP API anywhere that I can call on a per-HTTP
          transaction basis to see if the browser that is participating in the
          transaction is at that moment supporting cookies?
          3. There are times when my framework needs to delete a cookie by setting
          its maxAge to 0. Most of time time this works, but (as with the session
          ID/URL rewriting above) occasionall the cookie does not get deleted on
          the client brower machine. This screws up some of the application logic
          that I have in the framework. Is this related to the problems listed
          above?
          CONCLUSION
          Any and all information is appreciated, from anyone. Thanks!
          Chris


          Hi,
          To answer your question #1, yes I have seen this behaviour, and
          the explanation I feel is as follows.
          1] You access a resource on WL Server & it starts a session, at
          this moment it is not sure whether the browser supports cookies
          so it uses both methods, URL Writing & cookies to store the session
          ID
          2] On the next request, it tries to read the cookie, if it is able
          to read it that means cookies are enabled and there is no need
          to continue with URL Rewriting else it continues wioth URLRewriting.
          To answer Question #2, you can follow a procedure similiar to above
          to find out if browser supports cookies, ie set a cookie & in the
          next request try to read teh value.
          As far as Question #3 is concerned, try setting the magAge to -12
          hours insteda of 0 so that there is no problem even in case of
          a time difference.
          hope this helps

ACE module SSL url rewrite and path rewrite

Hi all,
I'm hoping some of you helpful people on this forum can guide me or suggest a solution to a problem I'm faced with.
I am currently load balancing exchange 2010 traffic via an ACE module. Software version is A2(3.3). I have most parts of it working fine however I am having an issue when it comes to SSL termination for Outlook Web Access (OWA).
The problem comes down to a HTTP header (field is location). I have configured an action list to re-write the SSL pure URL as per page 96 of the "Cisco Application Control Engine Module SSL Configuration Guide". example:
ssl url rewrite location bnecas\.mycompany\.com sslport 443
That part works, the http header location field that comes back from the GET request is changed to https://cas.mycompany.com which is great. However, in addition to that url, there is also a path or something following that part. The actual string that is returned is:
https://cas.mycompany.com/owa/auth/logon.aspx?url=http://cas.mycompany.com/owa/&reason=0
The first bit of it, (https://cas.mycompany.com) is changed by the ssl url rewrite command, however the last part (http://cas.mycompany.com/owa/&reason=0) isn't changed.
This is where I've been trying to get the http Header Rewrite command to do something. I don't know if it can work in conjunction with the ssl url rewrite function however with the ssl rewrite function it seems it can't change bits of the string that aren't the pure URL at the front.
The end result is that while I have an SSL connection to the OWA login page, when I do login to OWA it reverts back to HTTP. I'm fairly sure it is because of the last part of the location string above. Is there a way to change that location string to do the following:
1. change the first part of the string to be https://cas.mycompany.com (like the ssl url rewrite function)
2. change the last part of the location string to put https in there instead of http
Ideally I would love to have this string
http://cas.mycompany.com/owa/auth/logon.aspx?url=http://cas.mycompany.com/owa/&reason=0
replaced with this one
https://cas.mycompany.com/owa/auth/logon.aspx?url=https://cas.mycompany.com/owa/&reason=0
I had originally tried the following in the action list:
header rewrite response location header-value "(owa/auth/logon\.aspx\?url=)http(://bnecas\.thiess\.aus/owa/&reason=0)" replace "%1https%2"
ssl url rewrite location bnecas\.mycompany\.com sslport 443
but it didn't work. I'm probably screwing up the regex somewhere however there doesn't seem to be very clear examples anywhere I can find.
Any help will be greatly appreciated and of course I will be sure to rate every post that responds to my plea for help.

JavaScript URL rewritting in Enterprise Portal

Hi Experts,
I am working with EP and JavaScripts. We are making changes through JavaScript in Portal.
I have to rewrite the URL's with new URL's by using JavaScript. I am using the following code-
if( parent.document.body.innerHTMLindexOf(URL)>0)
rewriteLinks(sourceURL,targetURL);
if( parent.document.body.innerHTMLindexOf(URL)>0)
rewriteLinks(sourceURL,targetURL);
f( parent.document.body.innerHTMLindexOf(URL)>0)
rewriteLinks(sourceURL,targetURL);
But, the problem is screen is blinking for 3 times to execute the above 3 if()conditions. I think, for every if() the screen is reloading.
How to stop reloading for every if() condition? Once all the if() conditions executed, then only reload the screen.
Regards,
Vijay.

if you are using the rewriting the page then it will blink.
Workaround is use javascript to retrieve data to an invisible document and then do the content transfer to your visisble page using DOM.
This issue was purely javascript. My suggestion is to check with jsp forums for better results.

Random power off and screen blinking

I've had my droid for almost a year now and am very happy with it, but recently i've been having a few issues. Today it turned itself off in the middle of a phone call, my fingers were not near any button to cause this, and when I turned it back on I had half a battery. And about a week ago the screen wouldn't even load and stay black causing me to do a restart on it twice. Then the screen starts to rappidly blink and doesn't stop until I've tapped it like 5 times. I've uninstalled old apps i don't use to hopefully take some load off the phone but even at it barest it still messed up.

This may not help, but it won't hurt to try (it shouldn't erase any of your data) ... try a system cache clear:
Power down phone
Hold volume up/down & power simultaneously
Use volume down to navigate to 'Recovery', use volume up to select
Should see screen with triangle and exclamation point next to an Android
Press volume up/down simultaneously
Use volume rocker to navigate to 'wipe cache' and use power button to select
Once finished, use volume rocker to navigate to 'reboot system now' and use power button to select

APEX: Internet domain mapping / URL rewrite for Apps in the cloud

Hello,
I have registered for a trial access since first day in which the cloud was launched ... But, did not get access till now ... If I were to buy it, am I going to get access right away ??
Is Oracle Cloud going to offer Internet domain name mapping to a specific APEX application ???
Is Oracle Cloud u going to offer URL rewrite where APEX URL is not Search Engine friendly.... e.g:
This site: http://www.enkitec.com/ was built on APEX, but as you can see the URL was rewritten ????

Url rewriting & pagination

I am in the process of learning url rewriting, and with the help of a great book, 'Professional search engine optimization with PHP', i have got as far as rewriting category and product url's into keyword rich ones.
example at http://www.blunique.co.uk/Earrings-C1.html
where i am struggling is rewriting the url when i have the recordset results paginated, (using dreamweaver standard server behavior for repeat region).
Grateful for any advice.

Greetings,
I'll tailgate this similar question; I could use a guide to WLP 81x URLs. What does each parameter mean in file mode (.portal) and stream mode?
Any help here? Tips for understanding URLs would help Anders too.
tnx, curt

Regex help for URL rewriting

I have the following regular expression for rewriting a URL (from existing code which I had to make some quick changes)
String regex = "s#(href|src|url|action|background)=(\"?)(/|" + "http:originalserver.com" +"/|http.?://" + "originalserver.com"+ ")([^\">]*?)(\"?)#$1=$2" + "myserver.com" + "/$4$5#gis";
which does a URL rewrite and changes the URL from something like
src="http://originalserver.com/images/someimage.gif" to
src="http://myserver.com/proxy/images/someimage.gif"
Now I want to change this regex to add some parameters to the URL. ie.
case 1:
href="http://www.originalserver.com/index.htm"
to
href="http://www.originalserver.com/index.htm?myParam1=myValue1
case 2:
href="http://www.originalserver.com/index.htm?originalP1=originalV1"
to
href="http://www.originalserver.com/index.htm?originalP1=originalV1&myParam1=myValue1"
How can I change the regex to do this. As I have to do this fast and not an expert in Regex, any help would be appreciated.

Hi,
try this :
- first set delimiter (? or &) to append your parameters :
char delimiter = '\?';
String myParams = "myParam1=myValue1";
Pattern p = Pattern.compile( "\?" );
Matcher m = p.matcher( url );
if( m.matches() )
delimiter = '\&'; // not sure ampersand needs to be "backslashed"
- then use the modified regex
String regex = "s#(href|src|url|action|background)=(\"?)(/|" + "http:originalserver.com" +"/|http.?://" + "originalserver.com"+ ")([^\">]*?)(\"?)#$1=$2" + "myserver.com" + "/$4$5" + delimiter + myParams + "#gis";

I go to touch an app or game button on my iPhone and the screen blinks like its trying to open, but nothing happens. Why and what do I do to fix it?

Are there any apps in the muti-tasking bar? If the app closed unexpectedly and appeared in the muti-tasking bar, end it. Double tap the home button and then hold the app until it starts to wiggle then tap the minus at the top left at the app (if you want, end all the remaining apps) try opening them now. Hope this helps! :)

Please help - black screen blinking cursor 24" imac and XP home sp2

Brand new 24" imac purchased yesterday from the apple store with a 4 gig ram upgrade (i.e. all the newest stuff/versions). All updates installed & current.
Brand new (clean & scratchless) copy of Windows XP Home with SP2.
I ran the bootcamp assistant and made a 20 gig windows parition (so its under the 32 gig limit of fat32).
Following the installation procedure the windows disk is inserted, the machine reboots and then it just sits there with a black screen and a blinking cursor. The CD drive stops spinning and no progress from that point forward.
I then read on here some had better lucky with a "copy" of the original windows disk so I duplicated it in this Mac (i.e. burned with its own drive) but exactly the same problem with the burned copy (which also opens fine from within OSX).
I'm at a loss... where to go from here? We decided to try apple because they assured us we could run our "windows only aps" on the bootcamp side of the hardware but bootcamp isn't working!
Please advise...
If any of this helps:
OS X Version 10.5.2
2.8 Ghz Intel Core 2 Duo
4 GB 667 Mhz DDR2 SDRAM
Model name: iMac
Model id: iMac8,1

Welcome to the Apple forums:
Be sure your XP disk had SP2 embedded into XP, and not a separate file or patch.
Also be sure your disk is not an ISO image but a real disk, with files on it. You can look at them using your Mac. Insert the CD or DVD and doubleclick the disk icon.
You should see most or all of the following files and folders:
(HOMEWITHSP2)
AUTORUN.INF
DOCS
DOTNETFX
I386
README.HTM
SETUP.EXE
SETUPXP.HTM
SUPPORT
VALUEADD
WIN51
WIN51IC
WIN51IC.SP2
When you copied the disk, did you make sure your copy was Windows readable? Mac has several formats, one of which is Mac-only for data CDs. You need to select the universal mode, Mac and Windows for the data image and when burning the image.
Also be sure you selected to close or finalize the CD after burning or it cannot be read by Windows.

Gray screen when turning on iBook G4 with tiny file folder in center of screen blinking finder icon and question mark. I cannot figure this out. Tried everything I know. Can someone help please???

Hello,
Ideally you need to boot from the disk as you have no other media advisable. (e.g your hard drive)
Without some form of system disk or restore you wont be able to diagnose the problem with your hard drive.
By using a Mac OS X system disk you can load up the Disk Utilities and repair the hard drive if shown it's available. If it's not available you would need to replace the hard drive and reinstall Mac OS. Without any disk to support you, you are going to struggle.
You can obtain replacement disk, both retail copies or system disk on the Internet.
If you know what version of Mac OS X you had install (I'm guessing that it would have been 10.3, but would recommend 10.4) A retail disk is normally black with a colored 'X' on it, while system disk are always.
Always try and obtain a copy of the system restore disks (Gray) for your iBook
Ebay is another outlet that has genuine system disk for sell, but like any auction site, it's as and when someone is selling them.
The only other thing you could do is take it to a Apple repair agent who could check the hard drive on your behalf. That way you can get confirmation if the problem is the drive or some other fault. They may even help restore the OS for you.
I can't think of anything else to try without some form of disk to help you.
There maybe just one other small thing you could try.
When booting up, firmly rest your palm of your hand on the iBook next to the tracker pad on the left side.
If it works then it's another fault that I'm aware of.

Plumtree and Weblogic Portal Server | URL rewriting incompatibility

Hi All,
I am using Weblogic Portal as the Producer and Plumtree as the consumer for my WSRP portlets. I have enabled Producer URL rewriting. When i invoke an action URL i get a "Mode is not supported in this portlet." error. The template being passed is <blockingActionTemplate>/wsrpconsumer/pt_action?wsrp-navigationalState={wsrp-navigationalState}&wsrp-interactionState={wsrp-interactionState}&wsrp-mode={wsrp-mode}&wsrp-windowState={wsrp-windowState}</blockingActionTemplate>
and the URL generated is a href="/wsrpconsumer/pt_action?wsrp-navigationalState=&wsrp-interactionState=_action%3D%2FnewAction1&wsrp-mode=&wsrp-windowState="
The same portlet works fine when Consumer URL rewrting is enabled.
Plumtree is giving the same error for the portlets at the consumer at http://sunwsrp.dyndns.org/portal/wsrp/wsdl/default. Any help would be highly appreciated
Thanks

Hi, I don't have an answer on this but another more basic question. Our agency is using Plumtree Portal v5. I am assigned to develop a remote portlet. According to what I've read on the web as far back as 2003 Plumtree Portal supports WSRP but I'm getting conflicting answers within our agency. This post seems to indicate that the Plumtree Portal can consume WSRP compliant remote portlets. If that is correct, can you point me to documentation/examples? I've found reference to a Plumtree resource called "WSRP Portlet Consumer" for WSRP--does that still exist? Any help would be appreciated.
