Boa is an open-source, small-footprint web server that is suitable for embedded applications. Originally written by Paul Phillips, it is now maintained by Larry Doolittle and Jon Nelson.
Slashdot and Fotolog use Boa to serve images.
As of January 2006, Boa has the following limitations
- No access control features (HTTP Basic access authentication, etc.)
- No chroot option (planned)
- No Server Side Includes (deemed incompatible with server performance goals)
- No SSL support although there are some patches against 0.94.13 that introduce SSL support
