How to make an HEAD Http request in Crossrider extension?

Question

I would like to make a HEAD HTTP request to get filesize of the requested url, we can make HTTP GET requests using the below example code from Crossride Docs, my question is how to make a pure HEAD (with no data downloaded) request in croorider:

appAPI.ready(function($) {
    appAPI.request.get({
        url: 'http://example.com/api/get_something.json',
        onSuccess: function(response, additionalInfo) {
            // Display the response
            if (appAPI.utils.isObject(response)) {
                console.log('Response properties:');
                for (p in response) {
                    console.log(response[p] + ': ' + p);
                }
            } else
                console.log('Response: ' + response);

            // Stringify and display the response headers
            var headersAsString = '';
            for (var x in additionalInfo.headers) {
                headersAsString += '\n' + x + ': ' + additionalInfo.headers[x];
            }
            console.log('Response Headers:' + headersAsString);
        },
        onFailure: function(httpCode) {
            console.log('Failed to retrieve content. (HTTP Code:' + httpCode + ')');
        },
        additionalRequestHeaders: {
            myHeader: 'value'
        },
        responseDataType: 'application/json'
    });
});
