Aphid (the Apache/Perl HTTP Installation Daemon) provides a quick facility for compiling and installing the Apache Web server with support for SSL via mod_ssl, and with the embedded Perl interpreter provided by mod_perl. It downloads, compiles, and installs the software into the directory of your choice. Aphid places emphasis on providing an intuitive, browser-based interface and keeping a tiny distribution footprint. To date Aphid has been tested on Rehat Linux 6 and 6.2, FreeBSD 4.0, and Solaris 2.6 and 7.
Arachnida is an embeddable Web server. It uses the OpenSSL library and consists of a small framework for networking that allows you to asynchronously accept and handle connections using a "new connection handler" to handle new connections and a "data handler" to handle incoming data. This makes it possible to add support for any TCP/IP based protocol by just adding a handler. A test suite is included.
