I have written an html web page. I would like to put it on the apache server. So far im able to look up with http my docs on the server, however, i would also like to put this html document on the server and be able to assign it a file path that i choose as well. How in the world do i do this?

So far I have not been able to find where localhost/ is on my system? Please help me!!

My apache is installed under /var/lib/apache. Under that directory there is a directory called conf containing all the configuration files. In the file httpd.conf file there should be a line called "DocumentRoot" the directory after this will be the default directory for apache requests.
You can also setup different "virtual servers" that will route the request to a different directory depending on the url given. Even if you have only one domain name you still can route request like "manual.me.com" or "friend.me.com" to different directories.
It's very simple to setup. There are good comments in the httpd.conf file and the Apache manual is also great. It may be on your machine under the docs directory.
