I am developing an web application in C#.Net. It contains two pages. I the first page it does a lot of back end processing after that the session key values are sent to the next page for further processing. All the process is going correct when i gave small files for processing.For large files the session values are not comming to the 2nd page.I think session experiences the timeout problem. How can I overcome this problem?Please Help me.Thanks in AdvanceRamu Medida.
