This memo presents a number of known mechanisms used to direct client application requests to surrogate servers based on various policies. In this memo we group mechanisms commonly called request routing, content routing or content redirection under the term request mapping. There exist multiple request mapping mechanisms. At a high-level, these may be classified under: DNS Request Mapping, Transport-layer Mapping, and Application-layer Mapping.
