Answer 1

Solution: Make second argument of response.redirect(url,false);

Answer 2

In a bug I was investigating there was a Response.Redirect() and it was executing in an unexpected location (read: inappropriate location - inside a member property getter method).

If you're debugging a problem and experience the "Unable to evaluate expression..." exception:

1. Perform a search for Response.Redirect() and either make the second parameter endResponse = false, or
2. Temporarily disable the redirect call.

This was frustrating as it would appear to execute the Redirect call before the "step through" on the debugger had reached that location.

Answer 3

I had this same problem too, and it was tricky. For me, it was because I'm using Ext.Js javascript library. If you are doing a response.redirect in server-side code that you accessed in an Ajax call, there are problems. Ext.js has a workaround with their Ext.Redirect method.

Hello,

Request.Redirect(url,false);

False indicate : Indicate Whether execution of current page should terminate
