how to keep browser alive for hours?

[chunbo]

I use servlet to generate a big report which takes hours to finish. How to config tomcat so that the client side browser (IE) will keep alive even after 5 hours?

I tried to set the session timeout to 10 hours in web.xml, but the browser still die after about 2 hours.

Should I configure IIS as well?

Thanks

Can you not have the browser make the request, then the servlet kick off the report, and then have the browser pick up the report later (it could even poll your server for a status check intermittently) - this seems a more logical approach than keeping an HTTP connection alive for hours on end ...
