NetworkActiv Web Server (NAWS) is a small but functional web server. By default, it allows you to easy share your files with others, but you can also configure it to handle CGI, PHP and Perl (additional modules required). Since it supports byte ranges, it is suitable for streaming MP3 files. You can restrict access to the server by only allowing certain IP addresses, and/or by requiring that the visitors enter a password to get in. It comes with built-in support for multiple domain names and visitor statistics collection and visualization. Download the single EXE file to a folder of your choice. Rename it to NetworkActivWebServer.exe and launch by double-clicking. Select "Run self-contained program without installing".
