xmlrpc uncountered problem and solved under IE7

[vincent@…]

i needed to make xmlrpc, and i use an XHR instance with text/html header. But under IE7, i found that's this navigator override header content with application/urlencode followed by text/html... I solved my problem by adding an option in XHR class which provide the option for overriding header Content-Type (default:false). If set to true, Content-Type is set only to text/html as :

var myXhr = new XHR({ headers: {'Content-Type':'text/xml'},

method: 'post',
override: true,
onFailure: function() {console.log(this);},
onSuccess: this.handleEvent_receivedResponse.bind(this)

});

AND in mootools XHR.send:

if(this.options.override==true){this.headers = this.options.headers;}
else{$extend(this.headers, this.options.headers);}

It could be pretty god to have such an option in a future release, surely better implemented than mine.
