All Implemented Interfaces:

Closeable, AutoCloseable, org.apache.http.nio.protocol.HttpAsyncRequestConsumer<ResponseProducer>

public class RequestForTargetConsumer
extends AbsClientRequestConsumer

Specialization of AbsClientRequestConsumer to consume a client request that will be forwarded to a remote Target. This class examines the incoming request from the client to see if it is mappable to a remote Target. If no viable mapping can be found for the request, this class instructs it's ResponseProducer to return a 404 NOT_FOUND resoponse the the client.

RequestForTargetConsumer

public RequestForTargetConsumer(org.apache.http.protocol.HttpContext context,
                                org.apache.http.nio.protocol.HttpAsyncRequester executor,
                                org.apache.http.impl.nio.pool.BasicNIOConnPool connPool,

                                ScriptObjectMirror endpoint)

Primary constructor

Parameters:

context - Context of this request / response transaction

executor - HttpAsyncRequester which will perform the actual request to the remote Target and recieve it's response.

connPool - The client connection pool that will be used by the executor

patternTargetMapping - The mapping of relative uri paths to configured Targets.

dynamicHostMap - If non-null, this is a request modified by a JavaScript endpoint, *and* we are configured to allow the endpoint's to proxy to remote Target's not specified in the configuration file.

requestBuffer - Buffer used to read in the request content from a client (if any) which will then be flipped and sent out to the Target by the TargetRequestProducer

responseBuffer - Buffer used to read in the response content from the remote Target (if any) which will then be flipped and sent back to the client by the TargetResponseConsumer

endpoint - If non-null, the script endpoint which has interjected itself into this transaction.

Method Detail

requestReceived

public void requestReceived(org.apache.http.HttpRequest clientRequest)

Find a remote target that matches the requested uri, *or* return a 404 NOT_FOUND response if a mapping is not present.

UriToTargetKey

public static String UriToTargetKey(String remoteTargetUri,
                                    String[] scheme,
                                    String[] host,
                                    int[] port,
                                    String[] path,
                                    int[] stripPrefixCount)

UriToTargetKey

public static String UriToTargetKey(URI remoteTargetUri,
                                    String[] scheme,
                                    String[] host,
                                    int[] port,
                                    String[] path,
                                    int[] stripPrefixCount)

Break out a URI into it's component parts, and re-assemble them into a lowercase key representing the target.

Parameters:

remoteTargetUri - The input

scheme - "pass-by-reference" which if non-null will be populated with: https or http (if not explicitly https)

host - "pass-by-reference" which if non-null will be populated with: The name of the Target server.

port - "pass-by-reference" which if non-null will be populated with: The port the Target server is listening on (if not specified will be 80 for http and 443 for https).

path - "pass-by-reference" which if non-null will be populated with: The Path portion of the provided uri.

stripPrefixCount - "pass-by-reference" which if non-null will be populated with: This is actually an Integer.parse of the anchor portion of the uri which is used as a means to specify how much of the requesting uri should be stripped off before appending it to the host:port/path of the Target.

Returns:

A key that may be used to uniquely identify this remote Target.
