Thanks for pointing me to the ASP iRule and that is basically what I did.

The redirect issue is not isolated to WebSphere. It is actually an issue anytime the backend server does not listen on port 80.
With your WebSphere V5 issue it is most likely an issue in any WebSphere or J2EE/Java Server.
My guess is your applciations is using dynamically generated HTML using system varaibles. So the HTML has the host name and port that WebSphere is using, but that is not the host name that is used to get to the F5. So, as you did, you need to create a stream profile that replaces what WebSphere puts into the html code with what is needed to get back to F5.
I know I had this issue where we had a page that was dynamically created that had variables that were passed to a Java applet. Since the host name and port in the web page did not match the host name in the browsers URL, the applet did not work. So, one stream profile later and everything worked.
