Modular transparent proxy cache

A method performed by a computing device, the method comprising:

• receiving, by the computing device, traffic provided from a plurality of origin devices to a client device;
• determining, by the computing device, whether the traffic includes resources to cache in a cache server;
• and
• providing, by the computing device and to the cache server, addresses of the plurality of origin devices determined to include cacheable resources.

A computing device, comprising:

• a memory to store information regarding resources stored in a cache server;
• and
• a processor to:
• receive, from a client device, a request for a resource that is available from an origin device,
• determine, based on the information stored in the memory, whether the resource is likely cached in a cache server or not likely cached in the cache server,
• when the resource is likely cached in the cache server:
• forward the request to the cache server, where the cache server retrieves a cached resource based on the request and forwards the cached resource to the client device,
• when the resource is not likely cached in the cache server:
• forward the request to the cache server, where the cache server forwards a redirect command to the client device, based on the request, and where the client device obtains the resource from the origin device based on the redirect command.

A method performed by a cache server device, the method comprising:

• receiving, by the cache server device and from the request monitor device, requests for resources that match entries of a watch list that include addresses of origin devices with cacheable resources;
• adding, by the cache server device, the requested resources as candidate resources to store;
• retrieving, by the cache server device, the candidate resources from one or more of the origin devices;
• and
• storing, by the cache server device, the retrieved candidate resources, where the retrieved candidate resources may be served directly by the cache server device rather than by the one or more of the origin devices.

One or more non-transitory computer-readable media storing instructions executable by one or more processors of a cache server device, the media comprising:

• one or more instructions to receive, from the request monitor device, requests for resources that match entries of a watch list that includes address of origin devices with cacheable resources;
• one or more instructions to add the requested resources as candidate resources to store;
• one or more instructions to retrieve the candidate resources from one or more of the origin devices;
• and
• one or more instructions to store the retrieved candidate resources, where the retrieved candidate resources may be served directly by the cache server device rather than by the one or more of the origin devices.
