A peer group can be established for sharing Web cache data among a set of computing devices through a peer-to-peer network. The Web cache data can be used by each of the computing devices to respond to requests issued over a client-server network from a Web browser running on that computing device. Web cache data can be exchanged among the peers of the peer group via the peer-to-peer network. A client request issued from a Web browser of one of the computing devices can be satisfied using Web cache data obtained from a different one of the computing devices in the peer group. The client request can be a request to one of the Web servers for Web content. The server associated with the request may never provide the Web content responsive to the client request, which is obtained instead from the different one of the computing devices.

Provided is a Captcha Access Control System (CACS) for generating an improved captcha that are based, in one described embodiment, upon a command in one format and a response in a different format, one or both of which are rendered in a format that is difficult for an automated system to interpret. A computer system or program to which a user is requesting access generates a textual or audible command. A video device captures the user's response and transmits the response to a response evaluation device. Based upon an analysis of the transmitted video and a comparison between the analyzed video and the command, the computer or program either enables access or denies access.

One or more downloads of web content from one or more web content servers are monitored. A swarm is defined including one or more previous downloaders of the web content from the one or more web content servers. The one or more previous downloaders of the web content include one or more web content caches including at least a portion of the web content. Stored web content within the one or more web content caches of the swarm is tracked. A new downloader of the one or more web content servers is redirected to the one or more web content caches of the swarm.
