Hello. I'm having a bit of trouble grasping Yahoo's connection

manager.  I've had quite a bit of experience with our current

implementation of AJAX where we compile a string of XML on the

frontend and then pass that to a "service" as an EZMessage on the

backend. They then return us a response.



How do I achieve a similar goal with YUI's connection manager?  How do

I compile my information and submit it to a specific back-end service?

// I'm not familiar with the EZMessage format,

// so this is just a basic assumption that

// an XML document is all there is to the data.

var data = <your XML document here> ;



/*

  * if you need to send custom headers,

  * use YAHOO.util.Connect.initHeader(label,value);

  */



// Handle the response

var callback = {

   success:function(o){

     //do something for HTTP 2xx

   },

   failure:function(o){

     //do something for HTTP 4xx/5xx

   }

};



// Send the request

var request = YAHOO.util.Connect.asyncRequest(

    'POST',

    <urlToYourServiceHere>,

    callback,

    data

};

It works. I did, however, have to change _default_post_header: in

connection.js to "text/xml".
