Abstract

A device receives, from a client device, a request for a resource, and determines, based on information provided in the request, whether to terminate a connection for the request at the device. The device forwards the request to a network when the connection is not terminated at the device, and selects a target device for the resource when the connection is terminated at the device. The device also provides the request to the selected target device, receives the resource from the selected target device, and provides the resource to the client device.

store, in a data structure, information identifying the device based on the quantity of resources being greater than the threshold quantity of resources;

receive, from a client device, a request for a resource;

determine, based on information included in the request and the data structure, that the client device is requesting the resource from the device;

terminate a connection for the request at the network device based on;

the information identifying the device that is stored in the data structure based on the quantity of resources being greater than the threshold quantity of resources, and

the client device requesting the resource from the device;

determine, based on the connection for the request being terminated,

whether the resource is stored in the local cache;

select the local cache as a target device for the resource when the resource is stored in the local cache;

select the target device, from a plurality of devices storing resources, when the resource is not stored in the local cache,

the target device being selected based on one or more conditions of a network associated with the network device,

the one or more conditions including one or more of a bandwidth of the network or a load on the network;

provide, when the resource is not stored in the local cache, the request to the selected target device;

receive, based on providing the request to the selected target device, the resource from the selected target device; and

provide, based on receiving the resource from the selected target device, the resource to the client device.

11. The network device of claim 10, where, when determining that the client device is requesting the resource from the device, the processor is to:

extract at least one of;

a destination Internet protocol (IP) address from the request,

an IP address of the client device from the request, or

information identifying a destination port of the request, and

determine, based on the at least one of the destination IP address, the IP address of the client device, or the destination port, that the client device is requesting the resource from the device.

12. The network device of claim 10, where the processor is further to:

receive another request for the resource;

determine that the resource is being requested from another device; and

forward the request to the other device.

13. The network device of claim 10, where, when the resource is not stored in the local cache, the processor is further to:
