title: Add dynamic parameter in global.asax Application_BeginRequest
body: <p>I was reading this thread: <a href="http://sandblogaspnet.blogspot.com/2008/03/methods-in-globalasax.html" rel="nofollow">http://sandblogaspnet.blogspot.com/2008/03/methods-in-globalasax.html</a></p>
  
  <p>I'm trying send extra information in each request (in the <code>Application_BeginRequest</code>). Is possible add a new argument at this point before to excecute the request?</p>
  
  <p>The arguments are a custom guid (for tracking usages) and mobile detection.</p>
