Why the initial 302 redirect?

Question

I've been knocking around this problem with BEA for awhile now, with no
          resolution yet. Why does the initial request to my site first get a 302
          redirect page that then leads to the actual page I wanted served
          (index.jsp)? I don't have it configured to do any redirect, and the BEA
          engineers have told me that this is simply the way weblogic and other
          appservers are designed. DO most of the other appserver do this? Why can't
          it just be made to return the requested page right up front? They (the BEA
          engineers) claim that weblogic cannot be configured to do this.
          Oh, and the reason I ask is that we've been advised of problems with
          crawlers not following these redirect pages. Don't know if I believe that
          or not.

Hi himanshu1979,
<jsp:farward> is compulsary
String destination;
/* construct your destination url as you like */
this.getServletContext().getRequestDispatcher(destination).forward(request,
response);
Browser is showing ur jsp from the cache.
So you can instruct the browser not to do that by using
<code>
response.setHeader("Expires","0");
</code>
or
<code>
response.setHeader("Pragme","no-cache");
</code>
