Website that will let me run an HTTP Trace?

Question

I'm looking for a website that when given a URL will show you a trace of all the information that is sent when communication with this domain (e.g. HTTP headers). Specifically, I want to see how URL redirects are handled: what type of redirect is used (e.g. 301 or 302) and to what URL it is redirected to.

Answer 1

The Domain Dossier on CentralOps.net has a Service Scan option which does exactly that, among many other features.

This is the result from stackexchange.com

HTTP/1.1 200 OK
Connection: close

X-AspNetMvc-Version: 1.0
Cache-Control: private
Content-Type: text/html; charset=utf-8

and from google.com

HTTP/1.0 301 Moved Permanently
