title: OK to skip slash before query string?
body: <p>Is it safe to always skip the trailing slash when appending a query string?</p>
  
  <p>That is, can I use</p>
  
  <pre><code>http://example.com?querystring
  </code></pre>
  
  <p>instead of:</p>
  
  <pre><code>http://example.com/?querystring
  </code></pre>
  
  <p>? All webhosts I've used support this but is it safe to assume that all server environments will support this method? Is it standard?</p>
