Systems and methods of prefetching objects for caching using QoS
First Claim
1. A method for prefetching an object responsive to utilization of a connection, the method comprising:
- (a) storing in a cache, by an appliance, an object from a server communicated to a client;
(b) determining, by the appliance, that utilization of a transport layer connection established between the appliance and the server is below a predetermined threshold;
(c) prefetching, by the appliance, the object from the server via the transport layer connection in response to the determination and storing the prefetched object in the cache.

Abstract
The present solution provides a variety of techniques for accelerating and optimizing network traffic, such as HTTP based network traffic. The solution described herein provides techniques in the areas of proxy caching, protocol acceleration, domain name resolution acceleration as well as compression improvements. In some cases, the present solution provides various prefetching and/or prefreshening techniques to improve intermediary or proxy caching, such as HTTP proxy caching. In other cases, the present solution provides techniques for accelerating a protocol by improving the efficiency of obtaining and servicing data from an originating server to server to clients. In another cases, the present solution accelerates domain name resolution more quickly. As every HTTP access starts with a URL that includes a hostname that must be resolved via domain name resolution into an IP address, the present solution helps accelerate HTTP access. In some cases, the present solution improves compression techniques by prefetching non-cacheable and cacheable content to use for compressing network traffic, such as HTTP. The acceleration and optimization techniques described herein may be deployed on the client as a client agent or as part of a browser, as well as on any type and form of intermediary device, such as an appliance, proxying device or any type of interception caching and/or proxying device.

12. A system for prefetching an object responsive to utilization of a connection, the system comprising:
-
a cache of an appliance storing an object from a server communicated to a client; a detector determining that utilization of a transport layer connection established between the appliance and the server is below a predetermined threshold; and a prefetcher prefetching the object from the server via the transport layer connection in response to the determination, the prefetched object is stored in the cache. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
