Hi There,

The only reason I ask is that a prospective client uses a version of my website that uses the traditional ASP mechanism of uploading and downloading files and all works ok but when the prospective client uses the version of the website that uses the Ajax Uploader, the upload fails at 99% with the error message 'Flash: the upload task is interrupted! http 504'.

I believe it has something to do with their firewall but I don’t know what to tell them as I don’t understand the difference between ASP uploader and Ajax Uploader.
