title: Mechanize + Python: how to follow a link in a simple javascript?
body: <p>short: How to execute/simulate javascript redirection with python Mechanize?</p>
  
  <pre><code>location.href="http://www.site2.com/";
  </code></pre>
  
  <p>I've made a python script with mechanize module that looks for a link in a page and follows it.</p>
  
  <p>The problem is on a particular site that when I do</p>
  
  <pre><code>br.follow_link("http://www.address1.com") 
  </code></pre>
  
  <p>he redirects me to this simple page:</p>
  
  <pre><code>&lt;script language="JavaScript"&gt;{                                                                                         
      location.href="http://www.site2.com/";                                                                                           
      self.focus();                                                                                                                   
      }&lt;/script&gt;
  </code></pre>
  
  <p>Now, if I do:</p>
  
  <pre><code>br = mechanize.Browser(factory=mechanize.RobustFactory())
  
  ... #other code
  
  br.follow_link("http://www.address1.com") 
  for link in br.links():   
  br.follow_link(link)
  print link
  </code></pre>
  
  <p>it doesn't prints anything, that means that there is no link in that page.
  But if I manually parse the page and I execute:</p>
  
  <pre><code>br.open("http://www.site2.com")
  </code></pre>
  
  <p>Site2 doesn't recognizes that I'm coming from "www.address1.com" and the script does      not work as I would like!</p>
  
  <p>Sorry if it's just a newbie question and thank you in advance!</p>
  
  <p>p.s. I have br.set_handle_referer(True)</p>
  
  <p>EDIT: more info:
  Inspecting that link with Fiddler2 it looks like: </p>

  <p>so it seems to be a cookie problem?</p>
