HTTP proxy

From Glossary of Terms for Device Independence (2005-01-18) | Glossary for this source

An intermediary program which acts as both an HTTP server and as an HTTP client for the purpose of making requests on behalf of other HTTP clients.

HTTP requests are serviced internally or by passing them on, with possible translation, to other HTTP servers. An HTTP proxy must implement both the client and server requirements of this specification. A "transparent proxy" is a proxy that does not modify the HTTP request or the HTTP response beyond what is required for proxy authentication and identification. A "non-transparent proxy" is a proxy that modifies the HTTP request or HTTP response in order to provide some added service to the user agent, such as group annotation services, media type transformation, protocol reduction, or anonymity filtering. Except where either transparent or non-transparent behavior is explicitly stated, the HTTP proxy requirements apply to both types of proxies.

This term was developed from the definition of proxy in Hypertext Transfer Protocol -- HTTP/1.1.

proxy

From Web Characterization Terminology & Definitions Sheet (1999-05-24) | Glossary for this source

A proxy is an intermediary which acts as both a server and a client for the purpose of retrieving resources or resource manifestations on behalf of other clients. Clients using a proxy know the proxy is present and that it is an intermediary.

proxy

From Composite Capability/Preference Profiles (CC/PP): Structure and Vocabularies 1.0 (2004-01-15) | Glossary for this source

Software that receives HTTP requests and forwards that request toward the origin server (possibly by way of an upstream proxy) using HTTP. The proxy receives the response from the origin server and forwards it to the requesting client. In providing its forwarding functions, the proxy may modify either the request or response or provide other value-added functions. For the purposes of this specification, "proxy" refers to request/response forwarding functionality, which may exist in a stand-alone HTTP proxy or may be co-located with a gateway or origin server.
