Add a Query parameter in Mule
<p>Hi I want to add a query parameter Age = 23
I tried adding </p>

<pre><code>message.inboundProperties.'http.query.params'.Age = '23' 
</code></pre>

<p>In a expression  </p>

<pre><code>&lt;expression-component doc:name="Expression"&gt;&lt;![CDATA[message.inboundProperties.'http.query.params'.Age= '23';]]&gt;&lt;/expression-component&gt;
</code></pre>

<p>It won't work.</p>
