If you are installing WAMP on your Windows desktop computer, there are some things you can do to make it a better development environment and more natural to use.
Modify hosts file
In your c:/windows/system22/drivers/etc/hosts file, make the following changes:
This will force all references to itest.com and www.itest.com to go to WAMP. For Windows 7 users, you will need to run Notepad as an administrator to change this file.
Modify httpd.conf file
Enable virtual hosts in the httpd.conf file:
# Virtual hosts
Modify httpd-vhosts.conf file
Add the following to your httpd-vhosts.conf file. Replace the internal domain name with yours.
# Default virtual host that will bring up the WampServer home page
# Definition for iTest.com, our virtual host
#subdirectories and www canonical
ServerAlias www.iTest.com *.iTest.com
#the physical location
CustomLog "logs/iTest.com-access.log" common
If you want to add more virtual hosts, just repeat the recipe above.
