If you need to set up a secure, easily configurable Web server in as short a time as possible, then Abyss Web Server might just be the product for you. In development since 2002, its current version (2.5) runs on Linux, BSD, Windows, and Mac OS X. Its simple installation and setup (no obscure text configuration files) allows you to code your site with PHP, Perl, Python, Ruby, and even ASP.Net, if you're using the Windows version.
