Uploadify does not work on password protected sites

I use the JQuery plugin Uploadify开发者_运维百科 for uploading files. It works fine in all browsers. If however I imlement a passwort protection via .htaccess like this

AuthType Basic
AuthName "Restricted Files"
AuthUserFile /my/path/to/.htpasswd
AuthPGAuthoritative Off
Require user dev 

uploadify stops working in Firefox. In Chrome it still works.

In Firefox the file select box works, but after I selected a file the progress bar does stay at 0% and the file is not uploaded to the server.

I guess the issue is somewhere with flash on password protected sites. Any ideas how I can fix this, without removing the password protection?

There is a fairly well known flash bug that breaks authentication.

Read about it here (it's for swfupload, but I'm sure it applies to uploadify as well):

http://demo.swfupload.org/Documentation/#knownissues (under 'Cookie Issue')

You'll probably have to pass session information from the upload page to the upload script.

Workarounds are posted on the swfupload site, but I can't seem to find them anymore.

They have a demo of the flash bug here: http://demo.swfupload.org/v220/cookiebugdemo/index.php

I ended up excluding the uploadify directory from authentication (so everything is still password protected, except for the file upload).

To do so, I created a .htaccess file within the uploadify directroy with this lines:

allow from all
satisfy any
