```
protected static final byte[] pongMessageArray
```
    Pong message array.
  - getBodyMessageArray
```
protected final byte[] getBodyMessageArray
```
    GetBody message array. Not static like the other message arrays since the message varies with packetSize and that can vary per connector.
  - packetSize
```
protected int packetSize
```
    AJP packet size.
  - requestHeaderMessage
```
protected AjpMessage requestHeaderMessage
```
    Header message. Note that this header is merely the one used during the processing of the first message of a "request", so it might not be a request header. It will stay unchanged during the processing of the whole request.
  - responseMessage
```
protected AjpMessage responseMessage
```
    Message used for response composition.
  - bodyMessage
```
protected AjpMessage bodyMessage
```
    Body message.

```
    Host name (used to avoid useless B2C conversion on the host name).
  - tmpMB
```
protected MessageBytes tmpMB
```
    Temp message bytes used for processing.

```
protected MessageBytes certificates
```
    Byte chunk for certs.

```
protected boolean replay
```
    Replay read.
  - finished
```
protected boolean finished
```
    Finished response.
  - bytesWritten
```
protected long bytesWritten
```
    Bytes written to client for the current request.
  - keepAliveTimeout
```
protected int keepAliveTimeout
```
    The number of milliseconds Tomcat will wait for a subsequent request before closing the connection. The default is the same as for Apache HTTP Server (15 000 milliseconds).
  - tomcatAuthentication
```
protected boolean tomcatAuthentication
```
    Use Tomcat authentication ?
  - requiredSecret
```
protected java.lang.String requiredSecret
```
    Required secret.
  - clientCertProvider
```
protected java.lang.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.
