Hi,

If I put a try catch block for Server.Transfer call. It will catch a
System.Threading.ThreadAbortException exception like this. However, it
transfer the page to the correct page. Why did this exception occur?

Thanks.

Thanks for the info. But what is the purpose of raising this exception?

"Transfer calls End which raises a ThreadAbortException exception upon
completion."

It can be ignored.

So the rest of the current request isn't processed.

Personally, I think this is just a bad design on Microsoft's part, the whole
idea of pages posting data back to themselves would cause a lot of
unnecessary overhead if you just want to use Server.Transfer and not create
the whole input page again.
