Answer 1

+2 A:

If you're using HttpWebRequest, set AllowAutoRedirect to false. You'll then get to see the redirect yourself. Note that this only applies to HTTP-level redirects, not meta redirects within HTML.

(I don't know offhand whether it will throw an exception, but even if it does you can examine the response to find out the status code and the data including the redirection.)

Actually, it has multiple redirects, so you'd need to follow them through.

@Marc: Right. But at least you'd get to see each step of the way, and block it if necessary. It depends what the OP is trying to do.

Answer 2

+2 A:

If migre.me has some kind of an API, maybe they can provide you with a "preview" of the site you'll be redirected to.

If they don't, you'll have to create an HttpWebRequest and see the Uri of the response.

e.g.

WebRequest request = WebRequest.Create("http://migre.me/13rQa");
var response = request.GetResponse();

With that code, the response.ResponseUri property will have the address you'll be redirected.

Hope this helps you

I think @Jon's answer is better, because you won't have to download the target of the redirect (as you would have to do with my solution). Just use response.Headers["Location"] after setting the AllowAutoRedirect to false as suggested by Jon.

Actually, since there are multiple redirects involved, yours works and the `AllowAutoRedirect` approach *doesn't*.
