Relatively speaking, this "client site" becomes an intermediary between the original site and the client. The user can freely
navigate between the pages of the external site without leaving the "client site". The routing looks like
localhos/{user_site_name}/{routes_on_original_site}... The user can see the following statistics:
1. The number of clicks between the pages of the client's website
2. The amount of data that was sent and downloaded through the "client site"
