Abstract

Abstract A computer network including a client, at least one caching proxy server, and a destination computer is described. In a specific embodiment, a client computer may request particular types of information by including a category ID in request messages. In order to reduce network traffic, the destination computer may redirect the client's request messages to a caching proxy server, which is preferably located behind the same firewall or gateway as the client. The destination computer may initiate the redirection of client computer requests after receiving an HTTP proxy -- GET request message from the client. The destination computer sends a message to the caching proxy server specifying the categories of request that the client computer will direct to the caching proxy server. The proxy server forwards this message to the client computer. The client computer uses the information contained in this message to direct requests messages to a specific caching proxy server based on a category ID.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 89 words
A computer network, comprising: a first client computer to direct a request having categories; a first caching proxy server coupled to the first client computer, the first caching proxy server to receive a first data and to transmit the first data to the first client computer; and a destination computer coupled to the caching proxy server, the destination computer to transmit the first data to the caching proxy server, the first data to indicate which categories of the request the client computer will redirect to the caching proxy server.
Claim 2
Dependent Claim 89 words
A computer network, comprising: a first client computer to direct a request having categories; a first caching proxy server coupled to the first client computer, the first caching proxy server to receive a first data and to transmit the first data to the first client computer; and a destination computer coupled to the caching proxy server, the destination computer to transmit the first data to the caching proxy server, the first data to indicate which categories of the request the client computer will redirect to the caching proxy server.
Claim 3
Dependent Claim 25 words
The computer network of claim 1, wherein the client computer transmits a HTTP proxy -- GET request to the destination computer to initiate the redirect.
Claim 4
Dependent Claim 24 words
The computer network of claim 1, wherein the first proxy caching server returns a second data to the destination computer based on the request.
Claim 5
Dependent Claim 38 words
The computer network of claim 1, wherein the destination computer transmits a second data to the caching proxy server, and wherein categories of the request are redirected to a second proxy caching server based on the second data.
Claim 6
Independent Claim 72 words
A method of request handling, comprising: receiving a first data by a caching proxy server from a destination computer; transmitting the first data from the caching proxy server to a client computer, the first data to indicate which categories of a request the client computer will redirect to the caching proxy server; and directing the client request of the client computer to the caching proxy server based on the transmitted first data.
Claim 7
Independent Claim 72 words
A method of request handling, comprising: receiving a first data by a caching proxy server from a destination computer; transmitting the first data from the caching proxy server to a client computer, the first data to indicate which categories of a request the client computer will redirect to the caching proxy server; and directing the client request of the client computer to the caching proxy server based on the transmitted first data.
Claim 8
Dependent Claim 27 words
The method of claim 5, further comprising: receiving the request by the caching proxy server; processing the request; and returning a second data to the destination computer.
Claim 9
Dependent Claim 36 words
The method of claim 5, further comprising redirecting the request to a second caching proxy server by determining categories of the request that the first caching proxy server will redirect to the second caching proxy server.
Claim 10
Dependent Claim 16 words
The method of claim 5, wherein the first data is transmitted utilizing a TCP/IP compliant protocol.
Claim 11
Dependent Claim 25 words
The method of claim 5, further comprising transmitting a HTTP proxy -- GET request from the client computer to the destination computer to initiate redirection.
Claim 12
Dependent Claim 124 words
An article of manufacture comprising a computer usable medium having a computer readable program code means for redirecting a client computer request of a destination computer to a caching proxy server of the client computer, all of which communicate via a network, comprising: a first code segment for receiving a first data by the caching proxy server from the destination computer; a second code segment for transmitting the first data from the caching proxy server to the client computer, the first data to indicate which categories of the request the client computer will redirect to the caching proxy server; and a third code segment for directing the client request of the client computer to the caching proxy server based on the transmitted first data.
Claim 13
Dependent Claim 124 words
An article of manufacture comprising a computer usable medium having a computer readable program code means for redirecting a client computer request of a destination computer to a caching proxy server of the client computer, all of which communicate via a network, comprising: a first code segment for receiving a first data by the caching proxy server from the destination computer; a second code segment for transmitting the first data from the caching proxy server to the client computer, the first data to indicate which categories of the request the client computer will redirect to the caching proxy server; and a third code segment for directing the client request of the client computer to the caching proxy server based on the transmitted first data.
Claim 14
Dependent Claim 38 words
The article of manufacture as recited in claim 10, further comprising a fourth code segment for receiving the request by the caching proxy server, and for processing the request and returning a second data to the destination computer.
Claim 15
Dependent Claim 45 words
The article of manufacture as recited in claim 10, further comprising a third code segment for redirecting the request to a second caching proxy server by determining categories of the request that the first caching proxy server will redirect to the second caching proxy server.
Claim 16
Dependent Claim 22 words
The article of manufacture as recited in claim 10, wherein the network utilizes a TCP/IP compliant protocol for transmitting the first data.
Claim 17
Dependent Claim 34 words
The article of manufacture as recited in claim 10, further comprising a fourth code segment for transmitting a HTTP proxy -- GET request from the client computer to the destination computer to initiate redirection.
Claim 18
Dependent Claim 25 words
The article of manufacture as recited in claim 10, wherein the client and the caching proxy server have a private channel for sharing private data.
