title: URL format with GET parameters?
body: <p>Is there a specification somewhere listing the correct way to pass GET variables to a URL?</p>
  
  <p>Normally I do it like this (first variable indicated by ?, second and subsequent indicated by &amp;:</p>
  
  <pre><code>http://www.mysite.com/mypage.html?var1=value1&amp;var2=value2&amp;var3=value3
  </code></pre>
  
  <p>Are those ? and &amp; specifically needed, and in those order? Could I eliminate the '?' and pass all variables only with the '&amp;' ?</p>
