10.2.4. Modules and Apache HTTP Server 2.0
In Apache HTTP Server 2.0, the module system has been changed to allow modules to be chained
together or combined in new and interesting ways. Common Gateway Interface (CGI) scripts, for ex-
ample, can generate server-parsed HTML documents which can then be processed by
This opens up a tremendous number of possibilities with regards to how modules can be combined to
achieve a specific goal.
The way this works is that each request is served by exactly one handler module followed by zero or
more filter modules.
Under Apache HTTP Server 1.3, for example, a Perl script would be handled in its entirety by the
Perl module (
mod_perl
module — which serves static files — and is then filtered by
Exactly how to use this, and all other new features of Apache HTTP Server 2.0, is beyond the scope
of this document; however, the change has ramifications if the
document which is handled by a module that is now implemented as a filter, as each contains trailing
path information after the true file name. The core module, which initially handles the request, does
not by default understand
such information. As an alternative, use the

For example, the following is a sample Apache HTTP Server 1.3 directive:
VirtualHost _default_:443
# General setup for the virtual host
ServerName ssl.example.name
...
/VirtualHost
To migrate this setting to Apache HTTP Server 2.0, use the following structure:
VirtualHost _default_:443
# General setup for the virtual host
ServerName ssl.host.name:443
...
