Uploadify is a great tool. I'm using it so that people can mass upload photos for a photo gallery app I'm working on. This afternoon I've spent about 3-4 hours trying to get it to work on Windows (IE, Chrome, Firefox). It wasn't easy but I think I got it working in the end.
Pitfall no 1 (easy)
Pitfall no 2 (hard)
I've got nginx on the server passing requests to a Django daemon via FCGI. For some obscure reason, on Windows, if the file
uploader.swf was served as a static file directly from nginx it wouldn't work and I would get 403 errors that are never explained in the nginx error log or anything. So I changed it to let Django serve up the
file which obviously sets headers differently and then it worked.
Headers when served directly by nginx:
HTTP/1.1 200 OK Server: nginx/0.6.34 Date: Fri, 17 Jul 2009 17:01:09 GMT Content-Type: application/x-shockwave-flash Content-Length: 18659 Last-Modified: Wed, 08 Jul 2009 12:29:52 GMT Connection: keep-alive Accept-Ranges: bytes
Headers when served from Django (django.views.static.serve):
HTTP/1.1 200 OK Server: nginx/0.6.34 Date: Fri, 17 Jul 2009 17:01:03 GMT Content-Type: application/x-shockwave-flash Connection: keep-alive Last-Modified: Wed, 08 Jul 2009 12:29:52 GMT Content-Length: 18659 Vary: Cookie
Pitfall no 3 (super complex)
It was working in Firefox Linux, Safari Mac, Firefox Mac but not IE6 Windows, Firefox Windows or Chrome Windows. This despite having the latest (and same as Linux) version of Flash (10.0.22.x)!
Solution: In Internet Explorer, click on Options and delete the cookies, temporary Internet files and Clear History (for good measure). Now it works!!
It's been a hell of a journey but now it's crossed. Let's hope I can save some other poor sucker a couple of hours by making this blog available.
ow it's stopped working again. Works in Opera Windows but not IE 8 in windows 7. Grr...!
I've completely abandoned Uploadify now and instead gone for Swfupload which actually works really well.
