Systems and methods for preventing the caching of rarely requested objects

A system, comprising:

• a first set of one or more computers operable to determine a maximum offload potential for a first and a second class of objects;
• a second set of one or more computers operable to:
• provide cache admission logic at a proxy server, the cache admission logic including a first mode, in which an object is admitted to a cache of the proxy server in response to a single client request for the object, and a second mode, in which the object is admitted to the cache only after a plurality of client requests for the object;
• upon a determination that the maximum offload potential of the first class of objects is above a threshold value, apply the first mode of the cache admission logic in response to a client request for any of the first class of objects;
• and,
• upon a determination that the maximum offload potential of the second class of objects is below the threshold value, apply the second mode of the cache admission logic in response to a client request for any of the second class of objects;
• wherein each of the first set of one or more computers and the second set of one or more computers has circuitry forming at least one processor and memory holding computer program instructions for execution on the at least one processor to operate as specified above.

A non-transitory computer readable medium holding program instructions for execution on at least one processor, the program instructions comprising instructions to:

• provide cache admission logic at a proxy server, the cache admission logic including a first mode, in which an object is admitted to a cache of the proxy server in response to a single client request for the object, and a second mode, in which the object is admitted to the cache only after a plurality of client requests for the object;
• determine a maximum offload potential for a first and a second class of objects;
• upon a determination that the maximum offload potential of the first class of objects is above a threshold value, apply the first mode of the cache admission logic in response to a client request for any of the first class of objects;
• and,
• upon a determination that the maximum offload potential of the second class of objects is below the threshold value, apply the second mode of the cache admission logic in response to a client request for any of the second class of objects.
