Class ProxyFilter
java.lang.Object
net.sf.j2ep.ProxyFilter
public class ProxyFilter
- extends java.lang.Object
A reverse proxy using a set of Rules to identify which resource to proxy.
At first the rule chain is traversed trying to find a matching rule.
When the rule is found it is given the option to rewrite the URL.
The rewritten URL is then sent to a Server creating a Response Handler
that can be used to process the response with streams and headers.
The rules and servers are created dynamically and are specified in the
XML data file. This allows the proxy to be easily extended by creating
new rules and new servers.
