the loaded modules are

root@server:/etc/apache2/mods-enabled# ls
alias.conf authz_default.load autoindex.conf dav_fs.load ?dir.load negotiation.conf setenvif.conf
alias.load authz_groupfile.load autoindex.load dav.load env.load negotiation.load setenvif.load
auth_basic.load authz_host.load cgi.load dav_lock.load mime.conf php5.conf status.conf
authn_file.load authz_user.load dav_fs.conf dir.conf mime.load php5.load status.load
root@server:/etc/apache2/mods-enabled#
