Web Server

The web server is based on a standard FreeBSD 8.2 installation with the following additional configuration.

Apache, etc.

portmaster devel/git                                # disable everything but ICONV, CURL
                                                    # ftp/curl: disable IPV6, PROXY
portmaster net/rsync

portmaster www/apache22-worker-mpm                  # enable THREADS, SQLITE; disable IPV6, DAV, DAV_FS
                                                    # devel/apr1: enable SQLITE; disable IPV6, BDB, GDBM
