Concepts

Cache objects are primarily identified by URI, this includes both URL and QUERY_STRING.

This cache is shared by all users.

This cache stores objects for individual clients.

You may need to save different variations of the same URL. Traditionally, this is set by a “Vary” header, for “transfer-encoding”. This is not enough for current web applications, so we expand it with LiteSpeed-specific response headers and rewrite rule environment variables.

This can be used to store multiple cache copies based on User-Agent (desktop/mobile view), multi-language, multi-user classifications (registered vs guest), visitor geographic information, etc.
