session-timeout

I got this error when i access my hosted web application(in VS2008 C# ASP.NET 3.5 Framework) Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. The interesting thing is that there is no problem if we continue after login process. If you logged in and do nothing for 15 or 20 minutes, then click any menu...this error will be generated. So I doubt that it is related to session out. In my webconfig file I have written session time

I mean if the status is set to Online and you leave the page, it will remain Online you may

Where does classic ASP store the value for session timeout? I have looked through the code and this classic ASP website isn't using Global.asa(so no "Session_OnStart") or Session.timeout=x. The website is hosted on IIS 7.On IIS for this website,in Features view,double-clicking on "ASP" -> Session Properties -> Enable session is set to 'True' and the Time-out value is set to 20.

I want to unset/delete my existing cookie with this: setcookie ("user", "", time()-1); unset($user); But cookies can not be deleted or unset. So what is problem? you can unset cookies this way only may -1 not work try this setcookie ("user", "", time() - 3600); emavens When deleting a cookie you should assure that the expiration date is in the past.

I have a problem with timeout. firstly the timeout happens every 20 minutes on server even if the time in webconfig is set to 120 mins. second, when the timeout happens it goes to the login page, which is correct but on logging back in it sometimes goes to the default page and sometimes to the page it was previously on. I want it to go to the default page everytime.
