      com.cometway.httpd.ConnectionKMethod

public class ConnectionKMethod
extends KMethod

This class contains all the code which is needed to deal with an incoming HTTP connection. The WebServer creates this KMethod for each incoming request it receives. NOTES CONCERNING Keep-Alive connections: There are 2 fields in the AgentRequest that pertains to keep-alive connections, KEEP_ALIVE and KEEP_ALIVE_FIELD The KEEP_ALIVE_FIELD property is set by the ConnectionKMethod, if this property is NOT set, a Keep-Alive connection cannot be used The KEEP_ALIVE property is set by the agent that handles the request, if this property is set, the ConnectionKMethod will keep the connection alive The agent that handles the request is responsible for the following: It must return a content-length header in the response, this usually means the agent must return its own HTTP response If a keep alive is allowed, and the client wants a keep-alive, the agent must return the Connection: Keep-Alive field as well as the contents of the KEEP_ALIVE_FIELD property If a keep alive is allowed, and the client wants a keep-alive, the agent must set the KEEP_ALIVE property in the AgentRequest If a keep alive is allowed, and the client wants a keep-alive, the agent must NOT close the Socket or the Socket streams
