implement XHR level 2 for upload progress

[abdelaat]

Hi every body,

I am using extjs 3 and i want to implement file upload progress with xhr level 2, i already have code that uses a submit of a classic formpanel with a fileupload field, but with that implementation i can't have information of upload progress even if the browser supports XHR level 2, so what i want is to extend the formpanel and the fileupload field to use the XHR level 2 if supported by the browser else proceed with the old way. Can you give me some instructions on how to proceed.

Thanks in advance.

You will need to return info from the server, or use activeX to get progress upload features.
