openbsd webserver redirecting

[hack2003]

im new to openbsd and was using it with PF for a while.

now i wanted to use the apache server that im not that familiar with yet.
i iwas using clearos pfsense and other systems with nice gui to mange and i feel kind of lost now.


i have a great openbsd system that works as GW+FW but
there is something in the apache \php of openbsd that makes it take let say the index.php of mediawiki to my host name.. as lie test.mydomain/mediawiki .
in every other system i have installed apache i was diffrent.
any directions?

thanks.
