The Apache HTTP Server Project is an effort to develop and maintain
an open-source HTTP server for modern operating systems including UNIX
and Windows NT. The goal of this project is to provide a secure,
efficient and extensible server that provides HTTP services in sync
with the current HTTP standards.

Apache httpd has been the most popular web server on the Internet since
April 1996, and celebrated its 15th birthday as a project this February.

The Apache HTTP Server („httpd”) is a project of The Apache Software Foundation.

Get sources, unpack it and use a script (see attachement) to configure:

soft@hydra:~/apache% wget http://www.apache.net.pl//httpd/httpd-2.2.17.tar.gz
soft@hydra:~/apache% gtar -xf httpd-2.2.17.tar.gz
soft@hydra:~/apache% gsed "s/2.2.14/2.2.17/g" drf_httpd-2.2.14_conf > drf_httpd-2.2.17_conf
soft@hydra:~/apache% chmod 754 drf_httpd-2.2.17_conf
soft@hydra:~/apache% ./drf_httpd-2.2.17_conf
