How can i pass parameter from javascript to generic handler?
<p>I called generic handler (ashx) from javascript code as given below; </p>

<pre><code>var xmlHttpReq = createXMLHttpRequest();
            xmlHttpReq.open("GET", "hndlrCars.ashx, false);
            xmlHttpReq.send(null);
            xmlText = xmlHttpReq.responseText; 
</code></pre>

<p>But i have to pass parameter (dropdown selectedvalue) from .aspx to generic handler's "ProcessRequest" method.How can i do this?</p>
