Why is my asp.net application throwing ThreadAbortException?

Question

self explanatory question.

Why does this thing bubble into my try catch's even when nothing is wrong?

Why is it showing up in my log, hundreds of times?

I know its a newb question, but if this site is gonna get search ranking and draw in newbs we have to ask them

Answer 1

What does the stacktrace show?
Is there a pattern to it, or does it show up randomly?

Answer 2

This is probably coming from a Response.Redirect call. Check this link for an explanation:

(In most cases, calling Response.Redirect(url, false) fixes the problem)

Answer 3

The most common reason for a ThreadAbortException is calling Response.End, Response.Redirect, or Server.Transfer [1]. Microsoft has published some suggested functions that should be used in stead of those functions.

Answer 4

Has anyone else been able to resolve a situation like the original poster? I'm seeing the ThreadAbortException still being thrown, even when I set the Redirect or Transfer second parameter to false.

I've been trying various ways of using Server.Transfer, Response.Redirect and Server.Execute without success. It seems that regardless of how I try to achieve the transfer, I'm still getting the exception being thrown.

Answer 5

I have an entire article on this with what I think is a very good explanation and solution. Take a look. http://www.c6software.com/Articles/ThreadAbortException.aspx

Answer 6

As others have said, it occurs when you call Response.End() (which occurs when you call Response.Redirect without passing false as the second parameter). This is working as designed; typically, if you call Response.Redirect, you want the redirect to happen immediately. See this for more information:
