    `void` | `recycleInternal()`
    `protected void` | `resetTimeouts()` Provides a mechanism for those connector implementations (currently only NIO) that need to reset timeouts from Async timeouts to standard HTTP timeouts once async processing completes.
    `protected void` | `setCometTimeouts(SocketWrapper<NioChannel> socketWrapper)` Provides a mechanism for those connectors (currently only NIO) that need that need to set comet timeouts.
    `protected void` | `setRequestLineReadTimeout()` Configures the timeout to be used for reading the request line.
