Streamed from the origin server directly into cache storage.
Streamed from the origin server through the cache/proxy server
to the requesting client.
Streamed into the cache/proxy server and then split into
multiple broadcast streams.
The log sent by the cache/proxy server indicates the quality and
duration of the content that was received from
the origin server. The WMS Logging plug-in on the origin server can
be configured to request that client logs are forwarded to the
origin server upon receipt or are retained on the cache/proxy
server. If there are multiple cache/proxy servers between the
origin server and the client, logs will be transferred through any
intermediate cache/proxy servers to the origin server.
