Here is what I am looking for.
I want to have the ability to view a web page as if I am coming from a different country.
For instance, if I am in Canada, I want to see what my site looks like and what ads are running for people in Australia.
Input: URL - and country (or IP address)
Output: Webpage as if browsing in that country.
That's about it.
The only other functionality is that I want users to have to have user names and passwords to get access to the site.
