title: How to detect when a site check redirects to another page using the requests module?
body: <p>For example, if I go to <code>www.yahoo.com/thispage</code>, and yahoo has set up a filter to redirect <code>/thispage</code> to <code>/thatpage</code>. So whenever someone goes to <code>/thispage</code>, they will land on <code>/thatpage</code>.</p>
  <p>If I use <code>httplib</code>/<code>requests</code>/<code>urllib</code>, will it know that there was a redirection? What error pages?
  Some sites redirect user to <code>/errorpage</code> whenever the page cannot be found.</p>
