Class SupplyHandler

java.lang.Object

sunlabs.brazil.handler.SupplyHandler

All Implemented Interfaces:

Handler

public class SupplyHandler
extends java.lang.Object
implements Handler

Sample Handler for dispatching different users to different url's based on a special http authentication header. This is a re-implementation of the supplier.net content server using the new server apis (e.g. its not used for anything anymore). This handler was originally designed to be a "virtual web site", where credentials are passed in from an upstream proxy. Those credentials are used to provide different views based on the particular credentials supplied. The following configuration properties are used:

mapFile

properties file

prefix

url prefix

default

default map

header

http header (authentication)

realm

The authentication realm (basic)

init

public boolean init(Server server,
                    java.lang.String prefix)

Description copied from interface: Handler

Initializes the handler.

Specified by:

init in interface Handler

Parameters:

server - The HTTP server that created this Handler. Typical Handlers will use Server.props to obtain run-time configuration information.

prefix - The handlers name. The string this Handler may prepend to all of the keys that it uses to extract configuration information from Server.props. This is set (by the Server and ChainHandler) to help avoid configuration parameter namespace collisions.

Returns:

true if this Handler initialized successfully, false otherwise. If false is returned, this Handler should not be used.

respond

public boolean respond(Request request)

Dispatch and handle the request. This version looks at the supplier id, rewrites the url based on that supplier, then lets the default handler do it.

Specified by:

respond in interface Handler

Parameters:

request - The Request object that represents the HTTP request.

Returns:

true if the request was handled. A request was handled if a response was supplied to the client, typically by calling Request.sendResponse() or Request.sendError.
