The Apache/Perl integration project brings together the
full power of the Perl programming language and the Apache
HTTP server. This is achieved by linking the Perl runtime
library into the server and providing an object oriented
Perl interface to the server's C language API. These
pieces are seamlessly glued together by the mod_perl
server plugin, making it is possible to write Apache
modules entirely in Perl. In addition, the persistent
interpreter embedded in the server avoids the overhead of
starting an external interpreter and the penalty of Perl
start-up (compile) time.
Without question, the most popular Apache/Perl module is
Apache::Registry module. This module emulates the CGI
environment, allowing programmers to write scripts that
run under CGI or mod_perl without change. Existing CGI
scripts may require some changes, simply because a CGI
script has a very short lifetime of one HTTP request,
allowing you to get away with "quick and dirty" scripting.
Using mod_perl and Apache::Registry requires you to be
more careful, but it also gives new meaning to the work
"quick"!
Although it may be all you need, a speedy CGI replacement
is only a small part of this project. Callback hooks are
in place for each stage of a request. Apache-Perl modules
may step in during the handler, header parser, uri
translate, authentication, authorization, access, type
check, fixup and logger stages of a request.
