    --- | ---
    `protected String` | `clientCertProvider` When client certificate information is presented in a form other than instances of `X509Certificate` it needs to be converted before it can be used and this property controls which JSSE provider is used to perform the conversion.
    `protected InternalAprInputBuffer` | `inputBuffer` Input.
    `protected InternalAprOutputBuffer` | `outputBuffer` Output.
    `protected AprEndpoint.SendfileData` | `sendfileData` Sendfile data.

    `protected boolean` | `prepareSendfile(OutputFilter[] outputFilters)`
    `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.

- - ### Field Detail

    - #### inputBuffer

          protected InternalAprInputBuffer inputBuffer

      Input.

    - #### outputBuffer

          protected InternalAprOutputBuffer outputBuffer

      Output.

    - #### sendfileData

          protected AprEndpoint.SendfileData sendfileData

      Sendfile data.

    - #### clientCertProvider

          protected String clientCertProvider

      When client certificate information is presented in a form other than instances of `X509Certificate` it needs to be converted before it can be used and this property controls which JSSE provider is used to perform the conversion. For example it is used with the AJP connectors, the HTTP APR connector and with the `SSLValve`. If not specified, the default provider will be used.
