WE13 LATENCY REDUCTION VIA CLIENT-SIDE PIWFETCHING

The rapid growth of the WWW has inspired numerous techniques to reduce web latency. While some of these techniques have not been implemented because they either increase network rru$ic or require coapera-tion between tiers. recent studies cast a shndow on tech-niques already in use (e.g. proxy cachingl as U result of the increasingly dynamic aspects of the WWW. Znpartic-ular, the prol$erration of dynamically generated web pages (ie. cgi, ASP), which are either linked to a dah-base, or extract information from cookies. reduces the efectiveness of cucheing techniques. Most techniques attempt to improve on part of the overnll latency, and ojen neglecf io address the internal latency, which can Be a serious bottleneck in heterogeneous environments
