HttpWebRequest.Address vs HttpWebResponse.ResponseUri

Question

Whats the difference between these two properties?

To put into context, I am determining if a redirect occurs if our ResponseUri != RequestUri.

While a redirect occurs regardless the url http://adage.com/adages/article?article%5Fid=140560 will provide a different ResponseUri (http://adage.com/adages/post.php) than the Address (http://adage.com/adages/post?article%5Fid=140560).

It appears the ResponseUri takes the Content-Location header and uses it while the Address maintains the correct location.

Would it be correct to compare the RequestUri to the HttpWebRequest.Address to check for redirects?

Answer 1

Have you thought about setting request.AllowAutoRedirect=false and then reissuing the request on a redirect?

The Uri comparison should also work fine, although I am not sure of all the edge cases

Answer 2

Yes, comparing request.RequestUri and request.Address is the way to go. At least in Mono response.ResponseUri is the same as request.Address.
