Streaming Windows Media Encoding through ISA 2004


I have a web server using IIS to publish a website which simple shows a webcam being captured live using Windows Media Encoder over port 8080.  This works fine for all my internal users across my network.

I want to be able to view the webcam from the outside world.  I have ISA 2004 which I have configured to publish the web server using port 80 as normal.  When I try to view the site from outside of the corporate network, I get prompted to download the ActiveX as expected but then simply get a black screen where I would expect to see the contents of my webcam.

When monitoring the ISA box, I can see the request coming through and being passed onto the server as expected.  Everything seems OK except I then get a 304 Not Modified status returned.

I have turned off caching for this particular URL and also ensured the webpage showing the broadcast has a content expires attribute set to 0.  I've also tried adding rules for MMS and RSTP to see if that helps but nothing seems to make any difference.  Also seems to be next to no information available.  Is this really that hard to do?!

It's driving me nuts!!  Help!!

Thanks in advance...

Hi, just to let you all know I've managed to solve the problem.  Creating a protocol definition and then publishing the server did the trick.

PS Will request close and points refund.
