calling Response.End() after Response.Redirect()

Question

Is it necessary to call Response.End() after Response.Redirect(url)

Update

Thanks for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following:

Redirect calls End which raises a ThreadAbortException exception upon completion.

Answer 1

Response.Redirect calls Response.End for you

I don't agree its good practice - it leads to misleading code.

MSDN:

Redirect calls End which raises a ThreadAbortException exception upon completion.

The laws of HTTP explain that once a response is sent the server is done (no more code gets called)

Answer 2

Response.Redirect allows you to call Response.End.

Response.Redirect(url, true);
