title: Use ASP.NET WEB FORMS Server Side
body: <p>we're trying to "interact" with an old webapp using <strong>ASP.NET Web Forms</strong> from within our backend code. </p>
  
  <p>We're basically chaining a few POST calls over to this ASP.NET part and then parsing the HTML we get back.</p>
  
  <p>We're having troubles with this <strong>__VIEWSTATE</strong> hidden input (looks like for each POST/page change it changes). 
  Also after the initial GET we make to the page, we're saving the cookie we get back and use it for all the other POSTs.</p>
  
  <p>Anybody ever had to do something like this?
  Any suggestion would be very helpful.</p>
