A computer-implemented method, computer program product and computing system for receiving, on a second computing device, a read request from a user for web content local to the second computing device. An invalidation token is received for the web content local to the second computing device. The invalidation token includes a last modified timestamp for the web content local to the second computing device. The invalidation token is processed to determine if the web content local to the second computing device is substantially similar to web content local to a first computing device. If the web content local to the second computing device is substantially similar to the web content local to a first computing device, the web content local to the second computing device is provided to the user. If the web content local to the second computing device is not substantially similar to the web content local to the first computing device, the web content local to the first computing device is obtained and provided to the user. |

1. A computer-implemented method comprising:
receiving, on a second computing device, a read request from a user for web content local to the second computing device, wherein the second computing device is most geographically proximate to current location of the user; receiving, from a first computing device, an invalidation token for the web content local to the second computing device, wherein the invalidation token includes a last modified timestamp for the web content local to the second computing device and the first computing device includes a most updated version of the web content local to the second computing device; processing the invalidation token to determine if the web content local to the second computing device is substantially similar to web content local to the first computing device, wherein the web content local to the first computing device is the most updated version of the web content local to the second computing device; if the web content local to the second computing device is substantially similar to the web content local to a first computing device, providing the web content local to the second computing device to the user; and if the web content local to the second computing device is not substantially similar to the web content local to the first computing device, obtaining the web content local to the first computing device and providing the web content local to the first computing device to the user. |
