How to pass % in a URL query string?
<p>I am trying to pass a string via HTTP request which has one of the character as <code>%</code> in the URL query string. </p>

<pre><code>url = url + "?q=" + str + "&amp;block=" + block;  // str contains the '%' character
</code></pre>

<p>But on the ColdFusion page where I'm sending this information is returning following error:</p>

<blockquote>
  <p>Element Q is undefined in URL.</p>
</blockquote>

<p>Could you please tell me that how can I encode the <code>%</code> sign in a URL?</p>
