Systems and methods for injecting content

A method of determining whether provided content is present on a client device in a visitor based system where a client device accesses network content through a gateway device which allows a client device to access network content without requiring user reconfiguration of the client device, the method comprising:

• receiving a client content request at a gateway device from a client device, wherein the gateway device allows a client device to request and receive content without requiring user reconfiguration of the client device;
• sending gateway allowed content to the client device from the gateway, wherein the gateway allowed content appears to the client device as the client desired content;
• monitoring at the gateway device for a status indication of the content on the client device;
