The code is divided into two blocks, LSCACHE and NON_LSCACHE, and includes several rules for caching different types of resources, setting cache control headers, and modifying cache keys.
The LSCACHE block is specific to LiteSpeed’s caching mechanism, and includes rules for setting cache control headers and modifying cache keys for specific types of resources such as responsive images, JavaScript files, and fonts. It also includes a rule for disabling caching when certain cookies are present, as specified by the “banner” cookie.
The NON_LSCACHE block includes rules for setting cache expiry times for different types of resources using the Expires header. This block is not specific to LiteSpeed and can be used with any web server that supports the Expires header.
In summary, this code snippet is useful for configuring caching for a WordPress site on a LiteSpeed server, with rules for optimizing caching performance for specific types of resources and setting cache expiry times for others.
