title: jQuery: intercepting out going link and adding parameters
body: <p>When a user clicks a link on my page, I need to, before it gets actioned by the browser, add the param Hello=True to the url.</p>
  
  <p>So, the user clicks MyPage.aspx in  and gets sent to MyPage.ASPX?Hello=True instead.</p>
  
  <p>Has to be client side, preferably using jQuery</p>
  
  <p>I can add an attribute to the  tags if needed.</p>
