title: ASP.NET Request QueryString says value is null
body: <p>I have this link here...</p>
  
  <p><code>&lt;li&gt;&lt;a href="/?fileDownloadable=downloadableProducts/MyPDF.pdf" target="_blank" runat="server"&gt;MyPDF&lt;/a&gt;&lt;/li&gt;</code></p>
  
  <p>and in my code behind I try to a Request.QueryString["fileDownloadable"] and it says it returning null...which in the link its not..</p>
  
  <p>Any Ideas?</p>
