• Re: Invalid viewstate exception on ScriptResource.axd

  I found that application pool listed is DefaultAppPool and the recycling time is 1740 minutes. I don't think that the errors are co-releated to the time, I checked the rate of occurrence in the error log I found in one day there were 30 viewstate errors 20 of them took place from the time of 12:00 AM to 2:00 AM the rest 10 occurred from 4:00 AM till 11:00 PM in another day from 1:00 AM till 2:00 PM 14 times then from 3:00 PM till 10:00 PM 9 times, is this related to the recycling time?

  I don't think I would go with the solution of turning off the validation of viewstate. How would I know if the application pool of the web application is recycling? Thanks

• Re: Invalid viewstate exception on ScriptResource.axd

  I've mentioned in my post that am not using web farm, this is the problem whenever I search for this topic, the invalid viewstate on scriptresource.axd I find people talking about the web farm and the machine key but as I already said, we are not using a web farm. Is this the only possible reason having this error means running a web farm? There is no other thing would cause this error? Thanks

• Re: Trapping Fileupload Size Error

  I've been facing the same problem, I wanted to redirect the users to an error page instead of displaying "Interner Explorer cannot display the webpage" when someone tries to upload a file greater than 4 MB which the default maximum request length, so I placed the same code of yours in the Application_Error event in global.asax with Response.Redirect instead of Server.Transfer but it never gets executed I still get the cannot display page. I've placed a breakpoint at Application_Error

• Re: Sending mail from web page

  I don't think that when two different users are accessing a page at the same time that trigger an email-send action is related to what's in msdn about an exception that occurs when SmtpClient.Send is called twice in a short time Here what's mentioned in msdn: "If there is an e-mail transmission in progress and you call SendAsync or Send again, you will receive an InvalidOperationException " I think this means if it's in the same module or block of code like sending a message
