Distro Debian Sarge

When I type www.mydomain.net it resolves but ends up adding a directory to it:

http://www.mydomain.net/apache2-default/

Because I'm a paranoid nut and finally have the distro up and running, I was wondering how to stop it from adding the directory the proper way. Would deleting it be enough or do I risk messing something up?

I also have php and mysql running is there anything in the apache2.conf file that needs to me added or changed? The reason I ask is with apache 1.3 (on another install (woody)) there are lines in httpd.conf that were added. I pretty much followed the instructions for woody at www.falkotimme.com (Debian Setup) but now with sarge I thought I would ask here.

Also when I apt-get install webalizer it shows an empty file in /var/www and this did not happen with apache 1.3?? The directory tree was a little different.

Please and Thanks.
