Introduction:
In this article, i am going to explain about how to call a http handler/modules using ajax.

Main:
We can easily accessing the http handlers in the same way like normal pages using
post and get method.

local_xmlrequest = XMLlocal_xmlrequestuest();
local_xmlrequest.onreadystatechange = XMLlocal_xmlrequestuestCompleted;
local_xmlrequest.open("GET", "HttpModuler.ashx?Name=" +
document.getElementById('<%=txtName.ClientID%>').value, true);
local_xmlrequest.send(null);
 
// initialize XMLlocal_xmlrequestuest object
    function XMLlocal_xmlrequestuest() {
        var xmlHttp;
        try {
            // Opera 8.0+, Firefox, Safari
            xmlHttp = new XMLlocal_xmlrequestuest();
        }
        catch (e) {
            // IEBrowsers
            try {
                xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
            }
            catch (e) {
                try {
                    xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
                }
                catch (e) {
                    return false;
                }
            }
        }
        return xmlHttp;
    }
 
    function XMLlocal_xmlrequestuestCompleted()
    {
        if (local_xmlrequest.readyState == 4)
        {
            try
            {
                alert(local_xmlrequest.responseText);
            }
            catch (e)
            {
            }
        }
    }
