title: CGI script to set a cookie and reload
body: <p>I have a CGI script that gets some parameters in the URL, and presents a form.
  when the user submits the form, the information in the form is saved in a cookie.
  Now, on the press of the submit, I want the same URL to be called, including the parameters it was originally called with.</p>
  
  <p>Example: maybe be clearer:
  Someone calls me like this:</p>
  
  <p><strong>www.mysite.com/script.cgi?name=nec&amp;mail=necnec</strong></p>
  
  <p>On this page, user can choose color (red, yellow, green).
  When pressing button submit, I want my page to be called like:</p>
  
  <p><em><strong>www.mysite.com/script.cgi?name=nec&amp;mail=necnec</em>&amp;color=green</strong></p>
  
  <p>How I do this?</p>
  
  <p>Thanks!!!</p>
