Apache HTTP Server Version 2.3
htcacheclean
is used to keep the size of
mod_disk_cache
's storage within a certain limit. This
tool can run either manually or in daemon mode. When running in
daemon mode, it sleeps in the background and checks the cache directory
at regular intervals for cached content to be removed. You can stop the daemon
cleanly by sending it a TERM or INT signal. When run manually, a once off
check of the cache directory is made for cached content to be removed. If
one or more URLs are specified, each URL will be deleted from the cache, if
present.

option.If htcacheclean
is passed one or more URLs, each URL will
be deleted from the cache. If multiple variants of an URL exists, all
variants would be deleted.
When a reverse proxied URL is to be deleted, the effective URL is constructed from the Host header, the port, the path and the query. Note the '?' in the URL must always be specified explicitly, whether a query string is present or not. For example, an attempt to delete the path / from the server localhost, the URL to delete would be http://localhost:80/?.
htcacheclean
returns a zero status ("true") if all
operations were successful, 1
otherwise. If an URL is
specified, and the URL was cached and successfully removed,
0
is returned, 2
otherwise. If an error
occurred during URL removal, 1
is returned.
