Abstract

A document is sent from a document server to a relay server in response to a document request from a client. A script is then extracted from the document and is separately stored in a script cache. Then, a script calling portion in the document is substituted with a portion for calling the script stored in the script cache. Then, the resulting document is sent to the client. With this arrangement, when the script in the document is called by the client, it is executed by a script execution device of the relay server.
