Disable certain $http headers for an individual request

[groner]

I'm using $http with FormData to send multiple files, and I need to not set Content-Type, or the browser will not set Content-Type and the multipart boundary won't be known.

I can do this by saving, deleting, and restoring the header in $http.defaults.headers, but It would be a lot nicer to do $http.post(url, data, {headers: {'Content-Type': null}}).

@groner Kei, unless I'm missing something (which is probably the case!) it is already possible, check this jsFiddle: http://jsfiddle.net/4sCPp/4/

$http.post('/echo/json/', {}, {
        headers: {
            'Content-Type': undefined
        }
    });

Could you try to provide a bit more info about what is going on on your side?

This seems to be working fine now. I'm not sure what I did differently yesterday, but it's not happening now.

Here's what I'm doing if you're curious:

var fd = new FormData();
fd.append('foo', '123');

$http.post('/echo/json/', fd, {
    transformRequest: angular.identity,
    headers: {
        'Content-Type': undefined
    }
});

The request should include the header Content-Type: multipart/form-data; boundary=blahblahblah. I thought it sent Content-Type: application/xml when I tried this last, but I must have been doing something else different.
