I've recently started working with Apache 2.0.48. This question specifically relates to mod_disk_cache and garbage collection. I looked at the 2.0.49 notes, and don't see any significant changes noted.
The mod_disk_cache docs say (a) the mod is experimental, and (b) all of the GC directives are not yet implemented.
I searched the apache users mail archives back to Oct 2003, and found a few questions about the disk space growing unbounded, and the answers in both cases were to use something like a cron job to sweep the cache hierarchy and delete the old files. I've also searched the dev archives, and didn't find any answers.
I'm willing to get my hands dirty and write some code if need be. Given that the docs refer to a variety of GC directives that weren't implemented, I wonder if there is an original design floating around somewhere that could be made available, or if anyone can comment on plans for the mod_disk_cache, either in the 2.0 code tree or the 2.1 branch.
