Flash: The problem of uploading Firefox with Filereference has finally been solved.

Used to be a sentence like this:
var uploadurl:urlrequest = new URLRequest ();
Uploadurl.url = "upload.asp";

Test found on IE normal operation, but the upload failed on Firefox!

This morning inadvertently found that there is a website using filereference upload in Firefox test passed, I faint, it seems that my program problems.

After one hours in the afternoon, I finally found the reason:

Originally in IE browser, uploadurl.url can use relative path, but under Firefox, must use absolute path.

Workaround:

Get the current domain name

var domain:string = loaderinfo.loaderurl;     var i:int = Domain.indexof ("/flash");     if (i>0)    {     domain=domain.substr (0, i);    } var New  "/upload.asp";
