Before Rails 2.3.1 you could send a PUT request with application/xml contentType by appending ?_method=put to your HTTPServices url parameter. Unfortunately this stopped working. You can accomplish the same thing by sending a custom header of #X-Http-Method-Override# and setting it to PUT, or DELETE.
Example
If you have an update HTTPService like so:
<mx:HTTPService id="updateThing"
resultFormat="e4x"
url="http://localhost:3000/thing/{dataGrid.selectedItem.id}.xml"
contentType="application/xml"
method="POST"
result="index.send()" />
You would add your custom header like this:
/**
* @private
*/
protected function update_thing():void
{
var thing:XML = new XML(_thingXMLTemplate);
thing['first-name'] = firstNameInput.text;
thing['last-name'] = lastNameInput.text;
var headers:Object = new Object();
headers['X-Http-Method-Override'] = "PUT";
updatePerson.headers = headers;
updatePerson.send(thing);
}
*Note the headers['X-Http-Method-Override']
Same goes for sending a DELETE. Hope this helps.
