如何使用不同的主机实例化 HTTP 请求？

Question

Strange one here folks.

I'm studiying a web application's inner workings using Fiddler and have become a bit stumped. I'm requesting /account via the browser and Fiddler shows in the "Host" column website.local as expected since this is the URL the browser is pointing at.

Immediately after this a second request is made, however this time the host is services.website.com . I also cannot find any script in /account that makes this request.

So how can the Host change? Where is the response being sent to? Where can this be getting called from?

Answer 1

I'd expect that the server is sending a redirect to services.website.com : Fiddler isn't showing any redirects?

Answer 2

It depends on what really is in the first response that you receive. When you see a second request in Fiddler, does the page change too (in the browser)?

It will help a great deal if you could share the part of the Fiddler trace.
