I\'m using jQuery Fileupload to upload files. Its not sending headers that I set to the server. Why is the Authorization header missing onl
This answers my question,
Only browsers with support for XHR file upload support setting custom headers.
As a workaround in old browsers like our dear IE, you could set a cookie with the authentication token when the user authenticate and then get it in the server and verify it the same way you verify the header one. I know that it is not the most elegant solution but it works.
