## Abstract

A relay server is coupled to a URL database within an open firewall. First and second Internet devices are configured for communication with the relay server and include respective first and second websites behind closed firewalls, wherein the second website is operative as a “fallback” website to the first website. A web browser on a client Internet device is connected to the relay server. The relay server is provided with software to facilitate communication between the web browser and the first Internet device website so that if the first Internet device website goes offline, the relay server will connect the web browser to the fallback website on the second Internet device.

## Claims

### Claim 1

A system for a dynamic mobile web server fallback, the system comprising:
a relay server contained within an open firewall;
a URL database coupled to the relay server within the open firewall;
a first Internet device having a first relay agent configured for communication with the relay server, the first Internet device further including first web server software coupled to the first relay server for operating a first website behind a closed firewall;
a second Internet device having a second relay agent configured for communication with the relay server, the second Internet device further including second web server software coupled to the second relay server for operating a fallback website behind a closed firewall;
a web browser on an Internet device, the web browser being connected to the relay server; and
wherein the relay server is provided with software to facilitate communication between the web browser and the first Internet device website so that if the first Internet device website goes offline, the web browser will connect to the fallback.

### Claim 2

A method for a dynamic mobile web server fallback, the system comprising a relay server provided with software to facilitate communication between a web browser and a first Internet device website behind a closed firewall so that if the first Internet device website goes offline, the web browser will connect to a fallback behind a closed firewall
