htcacheclean is used to keep the size of
mod_cache_disk's storage within a given size limit, or limit on inodes in use. 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.

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/?.
By passing the
-A options to
htcacheclean, the URLs within the cache will be listed as they are found, one URL per line. The
-A option dumps the full cache entry after the URL, with fields in the following order:
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.
