Matchers

• A Matcher attempts to match an URI with a specified pattern for dispatching the request to a specific processing pipeline.

• Different types of matchers:

  • wildcard matcher
  • regexp matcher

• More matchers can be added without modifying Cocoon.

• Matchers help in specifying a specific pipeline processing for a group of URIs.
