title: Different postback URL being generated
body: <p>I have got two machines and one of them when I navigate to a page, the postback URL looks something like this:</p>
  
  <pre><code>&lt;form name="aspnetForm" method="post" action="./page.aspx?Action=nav&amp;amp;Page=4577" id="aspnetForm" enctype="multipart/form-data" autocomplete="off"&gt;
  </code></pre>
  
  <p>But on another machine, the same code renders a postback url without the "./" in the action attribute:</p>
  
  <pre><code>&lt;form name="aspnetForm" method="post" action="page.aspx?Action=nav&amp;amp;Page=4577" id="aspnetForm" enctype="multipart/form-data" autocomplete="off"&gt;
  </code></pre>
  
  <p>Any ideas what could be different?</p>
  
  <p>By different machine, I mean the same code deployed to different servers and then being browsed to from the same browser.</p>
