| proxy | A proxy server is an intermediate gateway that sits between a client PC and the Internet and provices forwarding/caching service, as well as security, logging and administrative control. A caching web proxy server saves content (such as Web pages) in its local cache the first time a request is made, and then serves the pages to other local clients from cache, without the need to forward the request to the Internet. Pages are only requested from the Internet if they are not found in cache. The proxy server forwards requests acting as a client, with its own IP address, and then in turn serves the pages to local clients. Caching proxy servers offer transparent service to clients, they can save bandwidth and improve performance, however they can also cause slowdowns when congested, as well as some problems delivering dynamic and secure content. |
