How to call a .net web service using mootools

Recently I have been trying the mootools library. One of the first task I wanted to be able to do, was to call a .net web service. The mootools ajax object defaults to urlEncoded = true. When method = post, and enlEncoded = true, then the content type is hard coded to application/x-www-form-urlencoded. To call the web service all you have to so it set urlEncoded = false, method = post, add the text/xml header, and add the SOAPAction header.


new Ajax('url here', {
method: 'post',
urlEncoded: false,
headers: {'Content-Type': 'text/xml; charset="utf-8"', 'SOAPAction': 'namespace/functionname'},
onComplete: function(webServiceResponse) {
// do something with webServiceResponse
},
onFailure: function() {
alert("ajax failure");
}
}).request('SoapEnvelope');
