How to download files using IE9 with HTTP protocol

I would like to do a file (of any kind) download using IE9 without any redirection. By redirection I mean providing a URL of the resource I am trying to download to the current document forcing a download if the MIME type is not a document type.

So I am left with getting the data using the XHR object and find a way to save it on disk. Since I am using IE9, I can't use any File API provided in IE10+.

So forget about:

Right now I am getting the data after the REST call and trying to write it into a document like in this post: Javascript Save CSV file in IE 8/IE 9 without using window.open()

But, the problem is document.write() seems to encode anything written to it in UCS-2, so binaries sent from the back-end are reinterpreted and the file gets corrupted. I am guessing that only text-based files could be saved then.

Last and not the least, I SHOULD not use flash.

Does anyone have an idea in mind to resolve the encoding issue or another technique to do the download?

If it can help, I am using angularjs as a front-end JS framework

For the limitation we had, passing the token as a parameter to get the file downloadable resource was the solution. When we uplift IE, we shall change the solution tough.

It implies removing any security chain filter and do a manual validation on the token in the backend.
