Thread was being aborted

Question

I am using Server.Transfer. Everything works fine, but exception log shows following exception.

System.Threading.ThreadAbortException: Thread was being aborted.
   at System.Threading.Thread.AbortInternal()
   at System.Threading.Thread.Abort(Object stateInfo)
   at System.Web.HttpResponse.End()
   at System.Web.HttpServerUtility.Transfer(String path, Boolean preserveForm)
   at System.Web.HttpServerUtility.Transfer(String path)

Any idea to avoid above exception.

Answer 1

This exception is throw by the call to Server.Transfer in order to halt the execution of the current method - exactly the same thing gets thrown if you do Response.Redirect.

The two choices you have are:

• Catch and rethrow the ThreadAbortException / reperform the Server.Transfer
• Make sure that you only do Server.Transfer in places where it wont be caught (recommended)

EDIT: Scratch that, http://support.microsoft.com/kb/312629 has a couple of other suggestions to try, but I still recommend #2 above.

Answer 2

Another way to solve this, is to catch the generated error and to not rethrow it:

        catch (ThreadAbortException)
        { 
        }

Answer 3

Caling Server.Transfer will call Response.End which always throws a ThreadAbortException. This is a "special" exception because while it can be caught in a catch block, it will always be re thrown at the end of the catch block. I would have your error logging ignore ThreadAbortExceptions.

Answer 4

This problem occurs in the Response.Redirect and Server.Transfer methods because both methods call Response.End internally.

Solution for this Problem is as follows.

For Server.Transfer, use the Server.Execute method instead.

Answer 5

Replacing Response.End() by the following helped fix the problem.

Response.Flush(); Response.Close();

Refer Can we use Response.Flush () instead of Response.End()

Answer 6

Replace Response.End() With HttpContext.Current.ApplicationInstance.CompleteRequest();
