 sunlabs.brazil.handler.GenericProxyHandler
All known Subclasses: sunlabs.brazil.handler.MultiProxyHandler, sunlabs.brazil.handler.ProxyPropertiesHandler,
| GenericProxyHandler | | public class GenericProxyHandler implements Handler(Code) | | Handler for implementing a virtual web site.
This causes another web site to "appear" inside our document root.
This classes is intended to be sub-classed, so some of the methods
in this implementation don't do too much.
All of the appropriate links in HTML documents on the virtual
site are rewritten, so they appear to be local references.
This can be used on a firewall in conjunction with
AclSwitchHandler to provide authenticated acces to selected web sites.
Properties:
- prefix
- URL prefix must match
- host
- name of host site to proxy to.
- port
- Host port to proxy to (defaults to 80).
- proxyHost
- Which proxy host to use (if any)
to contact "host".
- proxyPort
- The proxy's port (defaults to 80)
