    Are you saying that the first parameter of open() is optional, since by default it uses GET? So would it be something like req.open( url, true ); ? I intend to have seperate methods for POST, GET, and DELETE from the same URL. I am just trying to get GET working right now. My code does what I want in IE. Firefox and Opera are not playing nicely though. :-P

    Is there any way I can keep it as GET? I am trying to build a REST web service, so I want GET, POST, and DELETE to do different things. Thanks.

    I am trying to change my http Accept header to GET content I want from my server. I have been doing this with the setRequestHeader method. So far it does work, but only in IE using Apache 2 as a server. I have tried all combinations of IIS, Apache, Firefox, IE, and Opera. Is there something I am missing? I am happy serving with Apache, but I would like the code to work in all modern browsers.This is index.html: <html><head><title>Ajax test</title><script>function request(library){ var url = "/libraries/" + library; var req; // The request object try{ // Opera 8.0+, Firefox, Safari req = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ req = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ req = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Sorry, this page is currently not functioning or does not support your browser. Please try again later."); return false; } } } req.open( 'get', url, true ); req.onreadystatechange = function () { callback(req); } ; // setRequestHeader can only be called while in readystate 1 // We have to set the qvalue to 1.1 because Konqueror sends // it's standard Accept header with our header tacked on the end // which means that text/html gets picked first. // According to the w3c spec released in June 06, this method should OVERWRITE the Accept header req.setRequestHeader('Accept','text/xml; q=1.1'); // Above line only works in IE with Apache 2 for me! req.send(null); //modified per keelypavan suggestion}function callback(req){ if (req.readyState == 4){ alert(req.getAllResponseHeaders()); if (req.status == 200){ parseMessage(req); } }}function parseMessage(req){ var message = req.responseXML; var root_node = message.getElementsByTagName('name').item(0); alert(root_node.firstChild.data);}</script></head><body></body></html> If you are interested in the server code to handle the request, although it is not important, here it is: <?php$xmlData = <<< XMLDATA<xml><test> <name>working!!</name></test>XMLDATA;function printHttpHeader($mime){ header("Pragma: public"); header("Cache-Control: no-cache"); header('Content-Type: '.$mime);}/** * switch based on the header of the current request. This header was fetched * from the server and contents were put into these $_SERVER variables */if($_SERVER["REQUEST_METHOD"] == "GET"){ if(strstr($_SERVER["HTTP_ACCEPT"], "text/html")){ $mime = "text/html"; printHttpHeader($mime); print $_SERVER["HTTP_ACCEPT"]; exit; } //the goal is to change the request header so that only text/xml is the only value for Accept else if(strstr($_SERVER["HTTP_ACCEPT"], "text/xml")){ $mime = "text/xml"; //makes responseXML data available to the javascript printHttpHeader($mime); print $xmlData; exit; } }?> If you have any other questions, or any ideas, let me know. Thanks!
