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)         {          }
