9.4. Cache

filter cache

Arguments :

<name>      is name of the cache section this filter will use.

The cache uses a filter to store cacheable responses. The HTTP rules
"cache-store" and "cache-use" must be used to define how and when to use a
cache. By default the corresponding filter is implicitly defined. And when no
other filters than cache or compression are used, it is enough. In such case,
the compression filter is always evaluated after the cache filter. But it is
mandatory to explicitly use a filter line to use a cache when at least one
filter other than the compression is used for the same
listener/frontend/backend. This is important to know the filters evaluation
order.
