I am trying to set up a reverse proxy for apache, using mod_cache, mod_proxy and mod_rewrite. mod_cahche module from apache comes with htcacheclean which is an application that is suppose to take care of the cache by keeping it under a specify size.
The current cache size that I have been working with varies between 2 GB and 8 GB depending on the hour of the day and how much traffic is hitting the server. At this point htcacheclean is not able to clean it all in fact it doesn’t see more than 136 Mb or cache files, so it is unable to clean old files. I have been thinking of just create a script that will delete the output of: “find /cache/apache/ -atime +1” , allowing me to delete on a cron job any file that has not been accessed in the last 24 hours.
Here are the 2 questions that I have:
Q: it is possible that I generate more than 8 GB that has been accessed continuously in the last 24 hours, making it grow way more and be accumulated and reach bigger size. Can you think in a more efficient way to keep the folder /cache/apache blow an specific size, wile prioritizing the most frequently accessed files?
Q: Do you know an alternative to htcacheclean or what could be causing this failure (there are no errors on the log files)?
