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.
Boa is a single-tasking HTTP server. That means that unlike traditional Web servers, it does not fork for each incoming connection, nor does it fork many copies of itself to handle multiple connections. It internally multiplexes all of the ongoing HTTP connections, and forks only for CGI programs (which must be separate processes), automatic directory generation, and automatic file gunzipping. Tests show boa is capable of handling up to several hundred hits per second on a 100 Mhz Pentium, dozens of hits per second on a lowly 20 MHz 386/SX, and thousands on more powerful CPUs.
ctm.pl is a Perl script which generates Apache type maps for use with mod_negotiation. Useful if you have a lot of images available in different formats you need type maps for, especially if you don't want to use MultiViews to decide which of them will be sent back to the requesting browser.
fhttpd is an FTP/HTTP server with modules support. Modules run as separate "looping" processes locally or remotely, and can be configured to run under separate userids. Locally running modules can be configured to use fd passing of client's connection to avoid overhead in sending the response. ~username URL to directory remapping is supported in HTTP, and can be configured to access files, run scripts and modules under mapped user's userid.
FilterProxy is a Perl script that acts as a generic Web proxy. It is unique in that it allows you to install modules that can perform arbitrary transformations on HTML (or any other MIME-type) and HTTP headers. It filters ads by stripping HTML from the page, anonymizes requests by removing Referer and User-Agent headers, compresses HTML content, and de-animates animated gifs. Configuration is done via Web-based forms or editing a Perl data structure.
GeneWeb is a system for people who want to publish their genealogy data on the Web. It can also be used locally (not connected on the net) as a normal genealogy program. It uses very efficient techniques of relationship and consanguinity computing, speaks several languages, and can run in conjunction with an existing Web server (CGI) or standalone using its own internal server.
httptype reads a list of http hosts and optionally the port number for each of these. It queries each host, displaying the type of HTTP server running on that host, if any. It reads the http_proxy and no_proxy environment variables to determine whether to use a proxy or not. These options may also be specified through the command line.
Jellybean is a Perl Object server that allows people to write custom applications following a simple interface and framework. It's conceptually similar to Zope, but has peer communication potential. It has its own tiny Web server which serves static pages, CGIs, or transforms URIs into method calls on objects, and allows users to create their own behavior.
