Hi,
the next alpha release of Embperl 2.0 will have the ability to generate
Expired/Last-Modified headers and handle if-modified-since requests. The
programmer has to provide the time (in seconds) when a document should
expires and/or can provide a function, that tells Embperl if a document has
expired. Upon this data Embperl generates the headers (as far as possible)
and caches the output of the document (or subcomponent). Cacheing is already
working in the current alpha realase (2.0a16) and the http header stuff is
the next I plan to do.
I don't know if this is very usefull for a more general Module, because it's
all written in C and uses Embperl's internal DOM storage, but on the other
side Embperl 2.0 will not only be able to process his own syntax, but also
plain Perl, XML (e.g. XSP), and other custom syntaxes (e.g. SSI and others).
