PROXY SERVER A process providing a cache (A small fast memory holding recently accessed data, designed to speed up subsequent access to the same data. Most often applied to processor-memory access but also used for a local copy of data accessible over a network etc.) of items available on other servers (a program which provides some service to other client programs) which are presumably slower or more expensive to access. This term is used particularly for a World-Wide Web server (An Internet client-server hypertext distributed information retrieval system which originated from The European Laboratory for Particle Physics, High-Energy Physics laboratories in Geneva, Switzerland) which accepts URLs (Uniform Resource Locator which are often used in HTML documents to specify the target of a hyperlink which is often another HTML document or possibly stored on another computer) witha special prefix. When it receives a request for such a URL, it strips off theprefix and looks for the resulting URL in its local cache. If found, it returns the document immediately, otherwise it fetches it from the remote server, saves a copy in the cache and returns it to the requester. The cache will usually have an expiry algorithm (A detailed sequence of actions to perform to accomplish some task) which flushes documents according to their age, size, and access history. PROXY GATEWAY A computer and associated software which will pass on a request for a URL from a World-Wide Web browser such as Mosaic to an outside server and return the results. This provides clients that are sealed off from the Internet a trusted agent that can access the Internet on their behalf. Once the client is properly configured, its user should not be aware of the proxy gateway. A proxy gateway often runs on a firewall machine (A dedicated gateway machine with special security precautions on it, used to service outside network, especially Internet, connections and dial-in lines). Its main purpose is to act as a barrier to the threat of crackers. It may also be used to hide the IP addresses of the computers inside the firewall from the Internet if they do not use official registered network numbers.
