Forgive me for missing the obvious, but why not just use mod_file_cache for
this? I recall you mentioning that your use of mod_cache was for locally
caching very large remote files, so don't see how this would help that in any
case since the file doesn't exist locally when being stored, and if the file
is otherwise known to be on the file system, there's no reason to keep it in
mod_disk_cache's cache area (in any case, it wouldn't improve performance -
only mod_file_cache would). So what am I missing?
Apache Module mod_file_cache
Description: Caches a static list of files in memory
This has little to do with setup like ours (ftp.acc.umu.se):
* NFS backend with lots of storage (multiple TB), not lots of
bandwidth/performance.
* Multiple frontends with (relatively) fast cache storage.
* A working set of a couple of hundred GB which changes daily.
By using caching frontends we can easily fill our available 2Gbit even
though the backend can only do about 300-400Mbit. This is possible
because of a cache hit rate of about 90%.
