Hi Pete, I've already discovered the error. The error was caused because name resolution in domain. My code was correct and IIS too, but the network's configuration was wrong. Thanks my friend!!! :-D

Hi, My app is works correct when I access app with http://localhost/app. The session is sotored. When I access app with http://machineName/app, the session doesn't sotored. I believe that It is a configuratio, but where is?? IIS, Proxy, Web.config? Thanks, Sorry for my bad english!!!

People, I'm caming back because session in my app isn't working correctly. I did a simple code: in load method : session("test")= "hello world" in click button response.write (session("test")) What can I do?

I created a new page and used simple code testing session with string ("its my text"). The error ocurred. I'm thinking to myself that this error is in IIS!! Because it isn't ocurring in deployment!!!

Hi, The problem is continuing!!! I don't know like solve it. Thanks,

Ok, I'm going to see it. Thanks
