user types text in a text box, the text is sent to a php script with ajax. The response is used to populate a select menu. I am getting a xmlResponse is null error with some browsers.

Steps to recreate problem:

1. Goto Example page , in firefox/chrome.
2. type 's' in the text box
3. a menu should pop up, but instead I get xmlresponse is null (in firebug) .

The exact thing works on localhost on firefox/chrome but not when hosted. In Opera it works when hosted on localhost / internet.

Why ?

The xmlResponse -(copied from firebug)

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    
    <r><c><n>Sarvpriya Vihar</n><o>2</o></c><c><n>Sarvodaya Enclave</n><o>6</o></c></r>

The Code -

function handleKeyDownevent (e) {
                    mapimage.style.display = 'none' ;
                    e = e || window.event ;
    
                    if (xmlHttp) {
                      //  try {
                            //xmlHttp.open('GET' , 'async.txt', true ) ;
                            var target=  e.target || e.srcElement ;
                            var typed = target.value      ;
                            if (typed != ""){
                                ////console.log('sennding request') ;
                                xmlHttp.open('GET' , 'http://kutchbhi.x10.mx/ajax/choose.php?name='+typed, true ) ;
                                xmlHttp.onreadystatechange = handleServerResponse ;
                                xmlHttp.send(null) ;
                            }
                            else {
                                selectOption.innerHTML = "" ;
                                ////console.log(e.srcElement.value + "is blank") ;
                            }
                      //  }
                       // catch(e) {
                        //    //console.log('could not connect to server') ;
                      //  }
                    }
                    else {
                        ////console.log('error') ;
                    }
    
                }
    
                function handleServerResponse() {
                    if (xmlHttp.readyState == 4 ) {
                        if ( xmlHttp.status == 200) {
    
                           // try {
                                var xmlResponse = xmlHttp.responseXML ;
                                var  rootNode = xmlResponse.documentElement ;
