I think Servlets also use the CGI protocol, they accept POST and GET
strings the same way as any CGI program. They are just special server
side components written in Java that are run as a server process via a
'servlet' container, like Tomcat. Some servlet containers can run
standalone as a web server (Tomcat can), others, need to be run as a
process invoked by a web server like Apache via an intermediary module,
like mod_jk. Actually, Tomcat can be used as either of these. :-) Of
course, Servlets are specifically Java, CGI is a broader category that can
be implemented in any language.
Servlets are closer in principle to things like mod_perl, which embeds a
Perl interpreter into the web server. JSP, Java Server Pages, get
converted and then compiled into servlets in a manner very similar to the
way Mason converts components into compilable Perl code.
