5.1.3
CORS or Cross-origin resource sharing allows client-side JavaScript to make AJAX requests to another domain.
Fine Uploader has support for uploading and sending requests via CORS, but there are a few caveats depending on which browser is being used.
CORS in IE8 and IE9 is supported via the XDomainRequest
object. XDomainRequest
does not support setting the ‘Content-Type’ header
(or any headers for that matter) so for some server-side languages and
frameworks you are going to actually need to parse the request payload
programmatically rather than relying on the framework to do it for you.
