title: Boolean in a URI query?
body: <p>What is the preferred way to specify boolean value in the query part of URI? A normal query string looks like </p>
  
  <pre><code>a=foo&amp;b=bar
  </code></pre>
  
  <p>Say I have a parameter "c" with boolean value, should I state</p>
  
  <pre><code>a=foo&amp;b=bar&amp;c=1
  </code></pre>
  
  <p>Or </p>
  
  <pre><code>a=foo&amp;b=bar&amp;c=True
  </code></pre>
  
  <p>Or </p>
  
  <pre><code>a=foo&amp;b=bar&amp;c=true
  </code></pre>
  
  <p>I checked the query component section of <a href="http://www.ietf.org/rfc/rfc2396.txt" rel="noreferrer">RFC 2396</a> and it does not specify how to express a boolean parameter. So what I want to know is what is the common (or reasonable) way to do it?</p>
