“…HTTP/1.1 does not specify explicit connection-closing time, but provides only one example for a policy, suggesting using a time-out value beyond which an inactive connection should be closed [7,8]. HTTP/1.1 must decide when to terminate inactive persistent connections.…”

HTTP/l .I standard reduces latencies and overhead fiom closing and re-establishing connections by supporting persistent connections as a default, which encourage multiple transfers of objects over one connection. HTTP/l. 1, however, does not define explicitly connection-closing time but specifies a certain futed holdingtime model. This model may induce wasting server's resource when server maintains connection with the idle-state client that requests no data for a certain time. This paper proposes the mechanism of a heuristic connection management supported by the client-side under persistent HTTP, in addition to fixed holding-time model on server-side. The client exploits the tag information within transferred HTML documents so that decides connection-closing time. We compare them to the futed holdingtime model used in the current implementation of Apache Web server. An experimental evaluation of connection management policies, conducted using Web server logs, shows that our policy achieves 15-20% reduction on busy Web server in cost with respect to the fixed holding-time policy. As a result, the mechanism allows busy Web servers to use server resource more efficiently without additional server load and give services to clients more fairly.
