Abyss Web Server X1 is a personal Web server. Despite its small footprint, it supports secure SSL connections (HTTPS), CGI/FastCGI, ISAPI extensions, server-side includes (SSI), download resuming, caching negotiation, logging, custom error pages, password protection, IP address control, URL rewriting, aliases, custom MIME types, index files, custom directory listings, anti-leeching, and bandwidth throttling. It also features an automatic anti-hacking system and an intuitive multilingual remote Web management interface.
Das Schaefchen is a lightweight HTTP server and proxy for Unix platforms. It supports the minimum requirements of the HTTP/1.1 protocol and virtual hosts, basic authentication (which can be used to protect either files or directories), directory listing, byte ranges, reverse proxy, and FastCGI. It is an event-driven server that runs as a single process with a single thread using non-blocking I/O. It uses epoll as the event notification mechanism to multiplex control between active connections.
MKHINDEX generates HTML directory listings like the "Option Indexes" functionality of Apache. Other than the Web server, these listings are static. They greatly increase the performance of the Web server if you use it as a file server. MKHINDEX has been tested on Windows XP, Gentoo Linux, and Mac OS X.
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.
mod_jail is an Apache module that supports 1.3.x and 2.x branches. It is similar to mod_chroot, but uses FreeBSD's specific system call "jail", which is more secure than chroot. Thus, it is intended to run on FreeBSD only. This module allows you to run Apache in a secure jail easily, without creating a real jail environment containing a copy of /lib, /libexec, /usr/lib, etc. Also, it is able to change the securelevel within a created jail prison.
