School Guardian and Quicktime
One of our schools is having a strange issue with a the Quicktime movie embedded on the following URL:
A Day At The Great Exhibition - Victoria and Albert Museum
The plugin loads, does a countdown for buffering and then says '401 Not authorised'. I've added the vam.ac.uk domain to the list of domains not requiring authentication, and there's no longer any signs of denied requests in the filter log, yet it still won't play.
If I bypass School Guardian completely, and go straight through the upstream proxy everything works.
