title: URI starting with two slashes ... how do they behave?
body: <p>Lately I saw <strong>working</strong> code-blocks like this:</p>
  
  <pre><code>&lt;script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>And according to RFC 2396 (URI Syntax) and RFC 2616 (HTTP 1.1) these URI starting with two slashes are valid, but unfortunately the RFCs don't really explain them.</p>
  
  <p>Can anyone point me to a resource which explains how browsers will/should/do process these URIs?</p>
