The work presents a summary of Request-Routing techniques that are used to direct client requests to surrogates based on various policies and a possible set of metrics. In this memo the term Request-Routing represents techniques that are commonly called content routing or content redirection. In principle, Request-Routing techniques can be classified under: DNS Request-Routing, Transport-layer Request-Routing, and Application-layer Request-Routing.
