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.

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.
