public class RegexTargetHandler
extends ScopedHandler

A handle that uses regular expressions to select the target.

This handler applies a list of regex to target name mappings to the URIs of requests. If the regex matches the URI, then the mapped target name is used in the nested call to doScope(String, Request, HttpServletRequest, HttpServletResponse).

This handler should be installed as the first handler in a Context. It can be configured either with direct calls to addPatternTarget(String, String) or by setting the context init parameters "org.eclipse.jetty.rewrite.handler.REGEX_MAPPINGS" to a comma separated list of strings in the format regex==target.
