public interface IMediaCacheContextMapper
Interface for ContextMapper implementations
This interface is invoked via the ContextMapperClass configuration item in the
main MediaCache configuration section.
When the context mapper class implementation is in use the configuration parameters
URLEscapeStreamNameSpaces
URLEscapeStreamNameAll
are no longer implemented and it is up to the context mapper to implement these
if needed.

String getMediaNameFromContext(IApplicationInstance appInstance, IMediaStream stream, String basePath, String mediaName, String mediaExtension)
This is called each time a request is made into the MediaCache system for retrieval.
The input parameters provide a context of the request
appInstance - Application instance related to the client making the request
stream - IMediaStream object directly attached to the client
basePath - The current source base path the request will be services by. If this is empty then
no source was found for the request
mediaName - The asset name with the source prefixed, such as http/mp4:sample.mp4. This would indicate
the source with a prefix of http/ was being used.
mediaExtension - This is the extension of the asset, so commonly mp4.
The return parameter should be the mediaName needed to satisfy the Media Cache request. At this stage you can change/manipulate the mediaName to point to a different source, or even serve completely different
content if required.
If you do not want to do anything you can pass the mediaName directly to the output parameter.
