Class ReverseProxyHandler

java.lang.Object

org.forgerock.openig.handler.ReverseProxyHandler

All Implemented Interfaces:

Handler

public class ReverseProxyHandler
extends Object
implements Handler

A ReverseProxyHandler is a ClientHandler that is also responsible to turn RuntimeException into Status.BAD_GATEWAY response, as expected on the normal flow of request reaching the application when the proxy fails to connect to the backend application.

public Promise<Response,NeverThrowsException> handle(Context context,
                                                     Request request)

Description copied from interface: Handler

Returns a Promise representing the asynchronous Response of the given request. If any (asynchronous) processing goes wrong, the promise still contains a Response (probably from the 4xx or 5xx status code family).

A handler that doesn't hand-off the processing to another downstream handler is responsible for creating the response.

The returned Promise contains the response returned from the server as-is. This is responsibility of the handler to produce the appropriate error response (404, 500, ...) in case of processing error.

Note: As of Promise 2.0 implementation, it is not permitted to throw any runtime exception here. Doing so produce unexpected behaviour (most likely a server-side hang of the processing thread).

Specified by:

handle in interface Handler

Parameters:

context - The request context.

request - The request.

Returns:

A Promise representing the response to be returned to the caller.
