append parameter to segment/fragment request

Hi there,

We are passing a username paramater to our request for the flash manifest files on our CDN. This parameter is set at the streaming URL level.

e.g. http://server/{file}.{ext}?username={username}

this ends up as:  http://cdn/filepath/media_manifest.f4m?username=1234-1234-1234-1234-12 34

This works fine when retrieving the f4m's on the CDN until the player moves on and plays the first fragment and then the parameter is dropped.

Does anyone have a suggestion on how we can somehow retain or append the username on the fragment requests?

Thanks

Stu
