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 , automatic directory generation, and automatic file gunzipping. The primary design goals of Boa are speed and security. Security, in the sense of "can"t be subverted by a malicious user," not "fine grained access control and encrypted communications". Boa is not intended as a feature-packed server. Available rpmbuild rebuild options : --with : debug access poll --without : gunzip sendfile
