mod_perl到底是个什么
perl.apache.org
mod_perl brings together the full power of the Perl programming language and the Apache HTTP server. You can use Perl to manage Apache, respond to requests for web pages and much more.
mod_perl gives you a persistent Perl interpreter embedded in your web server. This lets you avoid the overhead of starting an external interpreter and avoids the penalty of Perl start-up time, giving you super-fast dynamic content.
As you'd expect from the Perl community, there are hundreds of
modules written for mod_perl, everything from persistent
database connections, to templating systems, to complete
XML content delivery systems. Web sites like
Slashdot and
Wired Magazine use mod_perl.
我想第一段红字是很重要的，她这个避免了用perl这种script语言写cgi脚本的天生的不足：需要每次启动Perl
第二段红字更重要，在Mod_perl框架内，更好的实现了CGI原来一些东西，比如Apache::DBI,只要增加一句话，就可以让mod_perl里边的db连接变成持久的。
