Projects / Boa


Boa is a single-tasking HTTP server. That means that unlike traditional Web servers, it does not fork for each incoming connection, nor does it fork many copies of itself to handle multiple connections. It internally multiplexes all of the ongoing HTTP connections, and forks only for CGI programs (which must be separate processes), automatic directory generation, and automatic file gunzipping. Tests show boa is capable of handling up to several hundred hits per second on a 100 Mhz Pentium, dozens of hits per second on a lowly 20 MHz 386/SX, and thousands on more powerful CPUs.

    Release Notes: This is primarily a "clean up" release, which means that most of the changes made are to improve the overall quality of the code, without introducing many new features. Some bugfixes were made and some new features were added, but the main changes were made to improve error checking for system calls and memory allocations.
