Claim:
1. A method in a proxy server to modify Internet responses, comprising: receiving, at the proxy server from a client device, a request for a network resource that is hosted at an origin server for a domain, wherein the request is received at the proxy server as a result of a DNS (Domain Name System) request for the domain returning an IP address of the proxy server instead of an IP address of the origin server, wherein the origin server is one of a plurality of origin servers that belong to different domains in which DNS requests for each of those different domains return the same IP address of the proxy server instead of IP addresses of the respective origin servers, and wherein the plurality of origin servers are owned by different entities; retrieving, by the proxy server, the requested network resource; determining, by the proxy server, that the requested network resource is an HTML (HyperText Markup Language) page; scanning, by the proxy server, the HTML page to locate one or more modification tokens, wherein each modification token indicates content that is subject to being modified; for at least one located modification token, automatically modifying, by the proxy server, at least a portion of the content of the HTML page that corresponds to that modification token; and transmitting, by the proxy server, the modified HTML page to the client device.
