I'm installing portable wampserver within my dropbox folder so I can access anywhere. I have this achieved and accessible using http://locahost:81

I want to access it by using a different address (dropping the :81 port number) such as http://myothersite.

I'm fairly certain I need to add a virtualhosts directove somewhere within this, but I am not Apache experienced!

This is the current Apache httpd.conf file:

ServerRoot "C:/Users/will/Dropbox/Wampee-2.1-beta-2/bin/apache/apache2.2.17"
Listen 81

ServerAdmin admin@localhost

ServerName localhost:81
