I have a Web Application, Websphere on AIX, using Servlets/JSP/Beans. Its uses Struts Framework.
If a request is taking a too long to execute (around 2 minutes) (say some DB Query is running for a long time), Internet Explorer (5.0) is automatically RESUBMITTING the request. I can see in Webspheres log that the same request has been received twice. Also Browser shows it is resubmitting the request (from Status Bar). Currently there is no Clustering being done. We are operating on Single Servers.
