title: How to get the client´s screen resolution in an interception context?
body: <p>I just intercept the client´s request using global.asax's <code>Application_BeginRequest</code> method to know if it is coming from <strong>ZZZ</strong> url to know if it should redirect to <strong>YYY</strong> or <strong>XXX</strong> page, depending its screen resolution.</p>
  
  <p>I read some posts/articles saying that to get the screen resolution I need to get it first by JavaScript.</p>
  
  <p><strong>Problem</strong></p>
  
  <p>As I´m in an interception context (the client may not walk by a page before), how to get the client´s screen resolution ?</p>
