Question about server on windows xp home.

Hello,
I've installed apache for windows, perl, and mysql on my spare xp box
(2.8ghz 2gb ram, two 250gb drives), my problem is this, I only want to run 2
sites, but we only have one ip address, and I've read up on it, but Im
totally lost, can anyone tell me what I have to put in my htttp.conf file
in this area:

# 127.0.0.1 is the TCP/IP local loop-back address, often named localhost.
Your
# machine always knows itself by this address. If you use Apache strictly
for
# local testing and development, you may use 127.0.0.1 as the server name.
#
ServerName mydomain1.com


# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at <URL:http://www.apache.org/docs/vhosts/>
<BEEN THERE, DIDNT HELP MUCH
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# Use name-based virtual hosting.
#
NameVirtualHost MYDOMAIN2.com

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.


# The first VirtualHost section is used for requests without a known
# server name.


<VirtualHost mydomain2:80>
ServerAdmin webmaster@mydomain2
DocumentRoot /www/docs/mydomain2.com
ServerName imydomain2.com
ErrorLog logs/mydomain2.com-error_log
CustomLog logs/mydomain2.com-access_log common
</VirtualHost>

Is this correct and once the domain2 propegates then it will find the site?
And would you do this if I wanted to add a third domain

Sorry, wrong group to be asking, alt. apache.configuration would be better.

My apologies.
