webfs

"Webfs (a.k.a. webfsd) is a simple HTTP server for purely static content. You can use it to serve the content of an FTP server via HTTP, for example. It can also be used to quickly export some files by starting an httpd server in a few seconds, without editing config files first. It knows how to use sendfile() on linux and FreeBSD. There is also sendfile emulation code which uses read()+write() and a userland bounce buffer; this allows one to compile and use webfs on systems without sendfile(). The stripped binary is less then 32Kb, making it great for floppy distros, recycled hardware, embedded systems (cramfs/romfs/flash disk) and other resource-limited environments."
