title: Mechanize form submission
body: <p>I have a website that I am attempting to scrape using Mechanize.
  When I submit the form, the form is submitted with an URL of the following format :
  <a href="https://www.website.com/Login/Options?returnURL=some_form_options" rel="nofollow">https://www.website.com/Login/Options?returnURL=some_form_options</a>
  (If I enter that URL in the browser, it will send me to a nice error page saying that the requested page does not exist)</p>
  
  <p>Whereas, if I submit the form from the website, the returned URL will be of the following format :
  <a href="https://www.website.com/topic/country/list_of_form_options" rel="nofollow">https://www.website.com/topic/country/list_of_form_options</a></p>
  
  <p>The website has a login form that is not necessary to fill in to be able to submit a search query.</p>
  
  <p>Any idea why I would get a different URL submitting the same form with Mechanize ? And how to counter that ?
  I cannot process the URL I get after "mechanizing" the form.</p>
  
  <p>Thanks!</p>
