Page Not Found - HTTP 400 Bad Request

Hi,

We have Web based application developed using Struts Framework and this application is deployed on Sunone Application Server. The application is accessed via  Siteminder as the authentication server.

The application works fine and when accessed through Web Browser (IE 6.0) on WINDOWS 2000   for North America Users.

Some users are based in Europe and they have access to this application through   VPN Network (Web Browser-IE 6.0 on WINDOWS 2000) .These users get “PAGE NOT FOUND “errors on the web browsers frequently, but on click of Refresh the page works fine.

This error occurs randomly all over the application, but no TRACES are reported in the Application Log and Server Log.

We did run tests from these locations using JMETER, but could not reproduce the errors.  This error is produced when user accesses the app through IE Browser and the Browser settings are same for all Users irrespective of locations.
 
Has anyone faced similar issues, any help would be very useful.

I think I've seen a similar issue in one of our applications which was being launched from a portal.
Eventually we've found out it had to do with Siteminder session cookies.
However, the solution was to log the application out programatically even when users crossed out of the browser window as an alternative to clicking the Logout button. Also we had to expire all cookies (again programatically) on the web server before redirecting to the main page thus receiving a fresh Siteminder cookie.

I hope the above gives you a lead.

I am afraid the posted answer is not the Accepted one , as the problem still persists and is very evidently related to Network Latency and Remote connectivity .
