AGGREGATION SERVER FOR CONTENT AND ITS AGGREGATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an aggregation server for contents capable of relieving a retrieval operation by a user. SOLUTION: Retrieval key information is periodically obtained from a key table 313. A server request is created by using the retrieval key information, and the server request is transmitted for every site server. When a server response including the retrieval result of a content is received from the site server, the retrieval result is extracted and delivered to a cache write part 312. The write part 312 writes the retrieval result into a cache table 317. When a client request is received from a client, a retrieval key is extracted and delivered to a cache retrieval part 310. The retrieval part 310 searches the cache table 317 and delivers the search result to a client communication part 309. A client response including the search result is transmitted to the client.
