We have a client that updated there Citrix environment to use the new 23.0.0.207 version of flex player. Since the update they have been seening the following issue, intermittently. Clearing the browser cache(s) doesn't fix the issue, the client must log out of their Citrix client and re-log in to fix the issue.

The issue is that, intermittently, when the client.html calls the to load the swf file the URL is missing the file name is should be http://production.com:8080/application-server/client-6.0.6-HF3-SNAPSHOT.swf

but is

http://production.com:8080/application-server/

Successful loading:

http://production.com:8080/application-server/client.html HTTP GET 200 text/html 5.86 KB 47 ms refresh

http://production.com:8080/application-server/history/history.css HTTP GET 200 text/css 0.68 KB < 1 ms <link rel="stylesheet">

http://production.com:8080/application-server/AC_OETags.js HTTP GET 200 application/javascript 8.74 KB 15 ms <script>

http://production.com:8080/application-server/history/history.js HTTP GET 200 application/javascript 24.28 KB 46 ms <script>
http://production.com:8080/application-server/client-6.0.6-HF3-SNAPSHOT.swf HTTP GET 200 application/x-shockwave-flash 4.11 MB 312 ms Flash

http://production.com:8080/application-server/graniteamf/amf HTTP POST 200 application/x-amf 0.55 KB 47 ms Flash

What is looks like when it fails:

http://production.com:8080/application-server/client.html HTTP GET 200 text/html 5.86 KB 47 ms refresh
   http://production.com:8080/application-server/history/history.css HTTP GET 200 text/css 0.68 KB 16 ms <link rel="stylesheet">

   http://production.com:8080/application-server/ HTTP GET 200 text/html 386 B 62 ms Flash

   The following client.html code has not changed is many years.

Any help would be greatly appreciated.

This is a race condition in your javascript. There's a template engine/jQuery thing that populates the stuff in between the ${ } tags. They're not getting populated before the browser processes those tags, so they're null in the requests. This doesn't have anything to do with Flash Player. Effectively, we're correctly requesting the URL that we're given. Actually, in this case, the browser is making the request, the SWF doesn't exist, and we never even get invoked...

The trick is going to be ensuring that when the browser processes this content, that it's actually populated. There are lots of ways to do this, but most of them will boil down to using javascript to add this stuff to the DOM in a controlled way where you can ensure that all of the data is properly initialized before the browser evaluates it.
