Embperl caches a lot of intermediate results by default to speed up generation of pages.
(For example compiled Perl code and compiled XSLT templates)
With Embperl is also possible to cache the output of pages or components. This is controlled
by parameters passed to the providers via recipes or as configuration directives inside
the page, passed to Execute or in your httpd.conf.
See Emperl_Cache_* and Embperl_Expires_* in Config.pod.
