POE component that manages and keeps alive client connections
POE::Component::Client::Keepalive creates and manages connections for other components. It maintains a cache of kept-alive connections for quick reuse. It is written specifically for clients that can benefit from kept-alive connections, such as HTTP clients. Using it for one-shot connections would probably be silly.
