CGI::Cache is a great little perl module that takes advantage of Cache::SizeAwareFileCache to enable web site caching …

Features:

• Can be easily added to any CGI script

• mod_perl compatible

• Rich control over caching policies

• Auto-generation of cache keys from CGI parameters

and believe me… it's FAST - much faster than 1 SQL query (except you need at least 1 live Query in your application) and zillions faster than n x SQL + n x XML-http requests …

The only problem in the latest version 1.4142

line 226

</p>

  # Set default value for max_size

  ->{max_size} = ::SizeAwareFileCache::NO_MAX_SIZE

	<p>

must be fixed with

</p>

  # Set default value for max_size

  ->{max_size} = ::SizeAwareFileCache::NO_MAX_SIZE

    unless defined ->{max_size};

	<p>

to make sure the maximum cache size is taken care of…

I just noticed this at a 94% full disk – carrying a 40+ GB disk cache :-)

so the latest version – probably all of the versions – simply ignore the setting for max_size and fill up your hard-disk until you unix demons crash because they can't write their logs… :-)

I wrote David Coppit – the author already, so expect a bugfix soon – meanwhile you can dare to edit your /usr/lib/perl5/site_perl/5.8.0/CGI/Cache.pm with this extra…

But be warned: cleaning a 40GB cache down to 1 GB or whatever you want it eats up all the server space… I will probably opt in for a compete rebuild of the cache over time to avoid an hourlong downtime here…
