I have setup a forum for podcasting with RSS and attachments,
The RSS feed works fine using iTunes, the only problem is that when the user clicks on a file they are prompted to login.
My suggestion as a resolution to this problem is to get the file.php controller to send back HTTP 1.1 authentication request which iTunes 7 will recognize, if the user authenticates properly then they will be allowed to download the .mp3 file.
Simply, file.php should check the url to see if:
1) the file requested is from a forum
2) the file requested is an .mp3 file
Then return back an http authentication request and process it accordingly if the above are true.
I’m interested to hear the communities feedback on this. Moodle really does other than the login page part seems to support pod casting!
