- 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.prefix=/foo/
A.host=www.foo.com
B.prefix=/bar/
B.host=www.bar.com
.
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/...
.

proxies
public static Hashtable proxies
- Holds all proxy -> prefix mappings for this server.
MultiProxyHandler
public MultiProxyHandler()
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 Handler
s 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
