com.netflix.http4.NamedConnectionPool

public class NamedConnectionPool
extends org.apache.http.impl.conn.tsccm.ConnPoolByRoute

A connection pool that provides Servo counters to monitor the efficiency. Three counters are provided: counter for getting free entries (or reusing entries), counter for creating new entries, and counter for every connection request.
