Outbound Proxy

Outbound Proxy: A proxy that receives requests from a client, even
though it may not be the server resolved by the Request-URI.
Typically, a UA is manually configured with an outbound proxy,
or can learn about one through auto-configuration protocols.


outbound proxy 는 client 가 요청한 것 받는다,
request-URI 로 서버가 신중하지 않을지라도 할 것이다.
