The caching protocol seems to check the cache size only on the specified interval. If you have a large cache and many users, this cache can grow very rapidly before apache even checks its size. Conversely, if you check the size too often and you have a very large cache (100MB+) then it takes too long to check the size. This combination makes it difficult to have a large cache for a proxy for a large corporation. >How-To-Repeat:
>Fix: Perhaps having the cache keep a running total of size and expire more often without the need to completely search the file system. Seems like CERN did something like this >Audit-Trail: >Unformatted:
