org.apache.ajp.RequestHandler
| RequestHandler | | public class RequestHandler extends AjpHandler (Code) | | Handle messages related with basic request information.
This object can handle the following incoming messages:
- "FORWARD_REQUEST" input message ( sent when a request is passed from the web server )
- "PING REQUEST" input message (sent by the web server to determine if tomcat is not frozen,
a PONG REPLY will be sent back)
- "RECEIVE_BODY_CHUNK" input ( sent by container to pass more body, in response to GET_BODY_CHUNK )
It can handle the following outgoing messages:
- SEND_HEADERS. Pass the status code and headers.
- SEND_BODY_CHUNK. Send a chunk of body
- GET_BODY_CHUNK. Request a chunk of body data
- END_RESPONSE. Notify the end of a request processing.

| | protected int | decodeRequest(Ajp13 ch, Ajp13Packet msg, BaseRequest req)
Parse a FORWARD_REQUEST packet from the web server and store its
properties in the passed-in request object.
Parameters:
req - An empty (newly-recycled) request object.
Parameters:
msg - Holds the packet which has just been sent by the webserver, with its read position just past the packet header (which inthis case includes the prefix code for FORWARD_REQUEST). | | public int | doRead(Ajp13 ch)

Parameters:
b - A buffer to fill with data from the request.
Parameters:
off - The offset in the buffer at which to start filling.
Parameters:
len - The number of bytes to copy into the buffer. | | public void | doWrite(Ajp13 ch, Ajp13Packet outBuf, byte b, int off, int len)

browser. | | public void | endSendHeaders(Ajp13 ch, Ajp13Packet outBuf)
| | public void | finish(Ajp13 ch, Ajp13Packet outBuf)
Signal the web server that the servlet has finished handling this
request, and that the connection can be reused. | | public int | handleAjpMessage(int type, Ajp13 channel, Ajp13Packet ajp, BaseRequest req)

Get more request body data from the web server and store it in the
internal buffer.
true if there is more data, false if not. | | public int | sendCPong(Ajp13 ch, Ajp13Packet outBuf)
| | public void | sendHeader(Ajp13Packet outBuf, String name, String value)
| | public void | sendHeaders(Ajp13 ch, Ajp13Packet outBuf, int status, String statusMessage, MimeHeaders headers)
