The invention discloses transparent proxy caching of resources. A device receives, from a client device, a request for a resource available from an origin device, and determines whether the resource is cached in a cache server. When the resource is cached, the device provides a first command instructing the client device to request the resource from the cache server, receives, from the client device, a first new request for the resource, and enables, based on the first new request, the client device to receive the resource from the cache server. When the resource is not cached, the device creates a firewall filter, provides a second command instructing the client device to request the resource from the origin device, receives, via the firewall filter and from the client device, a second new request for the resource, and enables, based on the second new request, the client device to receive the resource from the origin device.
