Php photo gallery TWG | JFUploader | TWG Flash upload | WFU | Forum

Setting: Joomla 3.6.2, PHP 7.0.10, IIS 7.5, JFUploader 3.2.4, Firefox 48

I just want to report an issue if uploads on a restricted IIS website do not work in Firefox.
I spent hours with it and perhaps someone knows an answer.

I have a IIS website which is setup for 'Windows Authentification' and known users - no anonymous access is possible.
In this case the uploads with JFUploader fails with error 401. I tried really a lot to fix this. I believed that I have a setting issue on server (IIS or PHP) because everything works fine if the website runs with anonymous access. Great mistake.

I prefer to work with Firefox and have this error with JFUploader extension only. After hours I tried the upload with Internet Explorer and what ... no problem. Make my day.

I would appreciate it if someone has a note for me. Thanks.

Have you tried the new html5 uploader already?

?? I do not know what you mean? I cannot see such a setting inside JFUploader.

Sorry. The html5 uploader is in twg not jfu.

But I'm not sure what the problem with firefox could be.

Best Michael

I tried all relevant NTLM authentication settings in Firefox without success.

What I not understand is what happens when I try to upload something.
Why is an additional handshake between JFU in Firefox and IIS necessary?
Why does this works in Internet Explorer? What makes the difference?
