LOAD BALANCING SYSTEM
First Claim
1. A communication system comprising a terminal, a contents server, a relay apparatus, and a management server connected via a network,the relay apparatus comprising:
- a communication relay unit for relaying a contents request transmitted from the terminal, to the contents server; and
a program location addition unit for adding a program location comprising a location and parameters of a source of a correction program which modifies information contained in response contents transmitted from the contents server in response to the contents request, to the response contents,the terminal comprising;
a contents request unit for transmitting the contents request;
a program request unit for transmitting a program request containing parameters indicated by the program location to the source of the correction program indicated by the program location and acquiring the correction program; and
a program execution unit for executing the acquired correction program, andthe management server comprising a program response unit for receiving the program request, generating the correction program according to the parameters contained in the program request, and transmitting the correction program to the program request transmitting terminal as a response.

Abstract
A relay apparatus adds a program location indicating a source of a correction program, to a response from a server requested of to acquire contents by the client, and transmits a response to the client. The program location contains tags identifying a response transmitting server and the relay apparatus as parameters. Upon receiving the response from the server via the relay apparatus, the client transmits a correction program acquisition request containing the parameters to a destination (management server) indicated by the program location. Upon receiving the request, the management server generates a correction program which rewrites a contents link, based on the parameters included in the request and transmits it to the client as a response. The client rewrites a contents link destination on the basis of the acquired correction program.
