Cache on demand

A method of transmitting content from a first computer device, the method comprising:

• (a) receiving a request for content from a cache computer device at the first computer device;
• (b) transmitting to the cache computer device the requested content;
• (c) receiving from the second computer device prediction of non-requested content that the first computer device will request based on the content requested by the first device;
• (d) transmitting to the cache computer device a cache request from the second computer device to cache the non-requested content on the cache computer wherein the cache request includes terms comprising an amount of cache memory requested to cache the non-requested content;
• (e) determining an amount of free space available on the cache computer wherein:
• (f) after accepting terms for the use of the cache memory, transmitting to the cache computer device the non-requested content, wherein the non-requested is content other than content requested by the cache computer device;
• wherein if the terms are not accepted, the second computer device is configured to receive a denial in response to the request for the use of the cache memo and the second computer device receives an amount of memory available to the second computer device.

A computer-readable medium containing computer-executable instructions that when executed perform the steps comprising:

• (a) allowing a request from a first computer device requesting content to be transmitted from a second computer device to the first computer device;
• (b) receiving from the second computer device, a prediction of non-requested content that the first computer device will request based on the content requested by the first computer device;
• (c) receiving at a cache computer, a first cache request from the second computer device to cache the non-requested content on the cache computer wherein the first cache request includes an amount of memory requested to cache the non-requested content:
• (d) determining an amount of free space available on the cache computer;
• (e) if the amount of free space available is more than the requested amount of memory to cache the non-requested content, caching the non-requested content at the cache computer, and
• f) if the amount of free space is less than the requested amount of memory to cache the non-requested content, transmitting a second cache request to the second computer device wherein the second cache request includes an amount of memory available to the second computer device.
