Flash player 9 and IIS 6

Since a couple of days, flv (video files) couldn’t be read from my website. It took me a while to find the issues.

The first one was trivial; the new security policy of the Flash player 9 was the reason. One need to define a crossdomain policy in order to make video files working correctly. The white paper can be found here.

The second issue was more tricky; with IIS 6.0, Microsoft changed the way streaming media is handled. Previous versions of IIS did not require any modification to stream Flash Video. Microsoft IIS 6.0, the default web server that ships with Windows 2003, requires a MIME type to recognize that FLV files are streamed media.

I hope it might help some of you.
