Catacomb is a WebDAV repository module for use with the Apache WebDAV module, mod_dav. Apache mod_dav parses WebDAV protocol requests into operations on a repository providing persistent storage of resources and their properties. The default repository for mod_dav is provided by a separate module, mod_dav_fs, which stores resource bodies as files in the filesystem, and stores properties in a (G)DBM database. Catacomb provides a replacement for mod_dav_fs called mod_dav_repos that stores resources and their properties in a relational database (MySQL). The primary advantage of this approach is the searching capabilities of the database are used to implement the DASL protocol.
mod_vhs is an Apache 2.2+ Web server module allowing mass virtual hosting without the need for file-based configuration. The virtual host paths are translated from any database supported by mod_ldap or mod_dbd at request time from MySQL, LDAP, PAM, or a system password file. PHP security can be basically auto-configured from the database using this module. Requests are cached by mod_ldap when configured.
The Apache/Perl integration project brings together the full power of the Perl programming language and the Apache HTTP server. With mod_perl 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 time.
rpaf changes the remote address of the client on incoming proxy requests. It is used in backend servers that needs to know the IP of the client, and works in conjunction with mod_proxy_add_forward (which sets the X-Forwarded-For header). When an X-Host header exists rpaf will take the hostname found here, put it into Apache, and update the virtualhost settings so that you can serve virtualhosts on the backend. It includes modules for both Apache 1.3 and 2.0.
The dkLab Apache is a patched Apache distribution for those who plan to use the Apache Web server to serve multiple separate sites working under different, fully separated, and independent Unix users. It does not require you to install any OS kernel modules or disable setuid, and works correctly and intelligently with KeepAlive turned on and MaxRequestsPerChild greater than 1.
ClearSilver is a high-performance, powerful, and language-neutral HTML template system. It enforces a separation between presentation code and application logic which makes writing, debugging, and maintaining Web pages easier. It can be used from C/C++, Python, Perl, Java, and Ruby.
