title: Regex for a custom 'HTTP GET style' request
body: <p>I'm trying to parse (Java) a custom GET style request, and I'd like to do that through a regular expression.<br>
  The request is formatted like: </p>
  
  <pre><code>GET myCommand?parameter1=value&amp;parameter2=value&amp;parameter3=value&amp;parameter4=value
  </code></pre>
  
  <p>The number of params is variable, but at least one param is required.</p>
  
  <p>Can someone help me with this regex? </p>
