All Implemented Interfaces:
Handler

public class MultiProxyHandler
extends GenericProxyHandler

Handler for permitting multiple cross connected virtual web sites. Each handler instance adds its prefix and destination to a static hashtable so the URL rewrite rules rewrite all of them correctly.

The GenericProxyHandler rewrites all of the links in each wepage to point back to the local. machine. Using this handler, if multiple virtual websites are configured, then links in one site that point to other virtual web sites are rewritten to point locally as well.

For example, suppose we have 2 MultiProxyhandlers A and B configured into the server as:

A local request for /foo/bar/test.html will fetch http://www.foo.com/bar/test.html. If the result is an html page, then any links in that page that resolve to www.foo.com/... will be rewritten to the local server as /foo/..., and any links that points to www.bar.com/... will be rewritten to /bar/....

MultiProxyHandler

public MultiProxyHandler()
Method Detail

init

public boolean init(Server server,
                    String prefix)
Initialize this handler. Add rewrite mapping into the global table. If any "virtual" web sites reference other "virtual" web sites, then rewrite the links accordingly.

Specified by:
init in interface Handler
Overrides:
init in class GenericProxyHandler
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.

addMap

public void addMap(MapPage map)
this gets called by the parent class.

Overrides:
addMap in class GenericProxyHandler
