/**
* A Connector is a component responsible receiving requests from,
* and returning responses to, a client application. A Connector performs
* the following general logic:
*
* - Receive a request from the client application.
*
- Create (or allocate from a pool) appropriate Request and Response
* instances, and populate their properties based on the contents of
* the received request, as described below.
*
* - For all Requests, the
connector,
* protocol, remoteAddr,
* response, scheme,
* secure, serverName,
* serverPort and stream
* properties MUST be set. The contentLength
* and contentType properties are also generally set.
* - For HttpRequests, the
method, queryString,
* requestedSessionCookie,
* requestedSessionId, requestedSessionURL,
* requestURI, and secure properties
* MUST be set. In addition, the various addXxx
* methods must be called to record the presence of cookies, headers,
* and locales in the original request.
* - For all Responses, the
connector, request,
* and stream properties MUST be set.
* - No additional headers must be set by the Connector for
* HttpResponses.
*
* - Identify an appropriate Container to use for processing this request.
* For a stand alone Catalina installation, this will probably be a
* (singleton) Engine implementation. For a Connector attaching Catalina
* to a web server such as Apache, this step could take advantage of
* parsing already performed within the web server to identify the
* Context, and perhaps even the Wrapper, to utilize in satisfying this
* Request.
*
- Call the
invoke() method of the selected Container,
* passing the initialized Request and Response instances as arguments.
* - Return any response created by the Container to the client, or
* return an appropriate error message if an exception of any type
* was thrown.
*
- If utilizing a pool of Request and Response objects, recycle the pair
* of instances that was just used.
*
* It is expected that the implementation details of various Connectors will
* vary widely, so the logic above should considered typical rather than
* normative.
