Why must braces ({, }) in a URL be escaped?
<p>What is the purpose of putting <code>{ braces }</code> in a url?</p>

<p>Can you please give an example of putting <code>{ braces }</code> in a url?</p>

<p>I encoded like the following to make it work in my applications, otherwise I kept getting an error</p>

<pre><code>Script = Script.Replace("{", "%7B");
Script = Script.Replace("}", "%7D");
</code></pre>
