Creating Custom Plug-ins
Windows Media Services consists of a core set of functionality that can be augmented and modified by the use of plug-ins. You can create the following types of plug-ins for your server.
Authentication plug-ins verify the identity of a client.
Authorization plug-ins establish a client's rights to access content.
Cache proxy plug-ins determine cache and proxy policy.
Data source plug-ins retrieve content from a source.
Event notification plug-ins handle events raised by the server.
Logging plug-ins log client and server information to a specific destination.
Playlist parser plug-ins create playlist objects that the server uses to determine what content it must send to a client.
