title: Trying to figure out origin of HTTP Request
body: <p>A web application is making a HTTP request and I cannot understand how it is making it. It makes it just after painting a page. There is no 302 in the previous requests and nothing obvious which will tell me how this request is being made.</p>
  
  <p>What would help is if I could set a breakpoint which would stop just before the next HTTP request is about to be sent. Then just after the page is painted, I'd enable this and figure out who is sending it Firebug lets me do this for XHR (Ajax) requests but not for normal requests. This is a normal HTTP request - not an AJAX one.</p>
  
  <p>Is it possible to do this with the debug tools in chrome or IE?</p>
