fserv is an HTTP server that can serve static files, act as a forward and reverse HTTP proxy server, and stream media content (SHOUTcast). It has a very high speed on all supported platforms due to its asynchronous I/O event architecture. It can easily process thousands of requests in parallel. When configured as a proxy server, it caches responses from upstream servers on a local filesystem, dramatically speeding up the response time when the same request is received again. fserv can act as an Internet radio trasmitter or it can re-transmit other Internet radio stations. In the latter case it also can record songs into MP3 files on a local machine, which makes it a useful music-grabber. The functionality of fserv can be extended by adding new modules. There is no installation needed. It's easy to configurate it, the fserv package comes with several default configuration files for common use-cases.
