title: Adding a condition in the url
body: <p>I would line to add a test condition in an asp.net form such that:</p>
  
  <p>1) From page1.aspx I manually add a query string parameter so that I can trigger the rest of the process in test mode like so: page1.aspx?test=true . This flag must be added in the query string.
  2) When I click on a asp.net button in page1.aspx, I am redirected to page2.aspx in test mode 
  because of teh attached querystring</p>
  
  <p>It seems that I have to work around the postback model of asp.net this is not very straight forward.</p>
  
  <p>Any idea how I can achieve the above behavior?</p>
  
  <p>Thanks</p>
