title: How is it possible a 404 response just only in IE8?
body: <p>I have an Spring application (with Spring Security and Spring MVC) deployed in a Tomcat server. The application works perfecty in Firefox, Chrome, Opera and IE9.</p>
  
  <p>I have a weird problem with IE8. The login screen loads, and (as I can see in server logs) the session is open when username and password are provided. Once the user is logged, and the browser is redirected to the main page, a 404 error is returned by the server.</p>
  
  <p>As IE8 developer tools doesn't have a net panel, I have used Fiddler to monitor http connections. I thought that it could be happening that it was doing a wrong request during page loading but it was the main page request wich is responsing with 404.</p>
  
  <p>How is it possible that the server responses with 404 to the main page request just only in IE8?</p>
  
  <p>Thank you.</p>
  
  <p>Edited:</p>
  
  <p>Those are the request header for IE8 and Firefox respectively:</p>
