Hi,
Async upload fails from IE (version 9 and lower) when used across different domains. Though, the file actually gets uploaded, but somehow onError event handler is called and an error message is showed in a popup.
It works fine for other browsers like FF and chrome, but HTTP OPTIONS method for the upload URL must be implemented by server side scripts, and the method must provide necessary response header like ("Access-Control-Allow-Origin", "some_allowed_domain") in it.
Any suggestions what specifically must be done to get upload work correctly with IE when used across different domains?
thanks in advance,
Piotr

Hello Piotr,

The upload uses a hidden IFRAME to perform the upload in IE. You get an error when it tries to access the response that originates from another domain.
We don't have a lot of options here. You can suppress the onError event, but you'll need other means to verify that the file is uploaded.
