How do I overrideMimeType in Openalyers.Request.Get

Question

I can't find any info on this. When performing a GET request with the following format, I cant figure out how to add the request for "overrideMimeType("application/xml")":

request = OpenLayers.Request.GET({
url: "http://aaaaaaaa.com",
async: true,
callback: request_handler,
});

An Openlayers request like this creates the request object and sends it all in this single code. I know if I weren't using the OpenLayers API, I would do something like:

request.overrideMimeType("application/xml");

But I can't get this to work using using my format. Any ideas? Thanks!

Yoy should use headers property of OpenLayers.Request object:

request = OpenLayers.Request.GET({
    url: "http://aaaaaaaa.com",
    callback: request_handler,
    headers: {
        "Content-Type": "application/xml"
    }
});
