httpico is yet another lightweight HTTP server. It implements a few HTML rewriting rules delineated by '<?pico>' tags, and makes it fairly easy to add more straight into the C code. It does not have complete HTTP standards compliance. It also contains a 'genstats' log analysis tool.
ashttpd was originally a testbed for a kernel async-sendfile patch. Today, it's just another Web server for serving static content rapidly. It differs from its competitors by storing its webroot in a database, which provides a 50% performance increase over using the operating system's VFS. It also allows precalculation of strong cache-validators (ETags).
