Hmm... we use the cpan module at work without hitch. But if there is
other solutions why are they not being put on CPAN ?
Anyway, my point is NOT to tie into one solution. The File Cache
method most cpan apache gallery type code uses is bad, but forcing
memcached only would be worse - as we may be dealing with terabytes
of images. In some places though where performance is key and usage
is small, then memcached - and of course the possibility of both for
The point is that there should be an Apache module for caching which
does all this for me - the problem with the modules available is that
they do everything themselves - so lots of repetition, lack of
Probably the best is to use something like Cache::Cache, write a
Memcached plugin for that (I started one but have not yet finished
it) and then have something like a Apache Cache plugin for
Cache::Cache as well - then you have a totally flexible solution.
I wonder if a cascaded Cache::Cache system could be implemented -
e.g. Memory -> Disk -> Original - so you have a way of caching the
most popular disk entries in memory (by memory that can of course be
