(Response.Redirect or Response.End) and 'Thread was being aborted' error

Just a short infomercial. Response.Redirect(url) is the same with Response.Redirect(url,true), which means that after the redirect, Response.End will be executed. In case you get a weird 'Thread was being aborted' exception, you probably have the Redirect/End methods inside a try/catch block. Remove them from the block and it will work. Probably the ending of the Response session doesn't look good to the debugger and that particularily obtuse exception is thrown.

If you absolutely must put the thing in a try/catch block, just put everything EXCEPT the Redirect/End. Another option (only for Response.Redirect) is to add a false parameter so to not execute Response.End.
