Directory of Sites for Proxy Pattern

http://sourcemaking.com/design_patterns/proxy

The site describes the purpose of the pattern and the problem it solves. It describes the four common scenarios when Proxy Pattern can be used by explaining the various kinds of proxies. It mentions the structure(UML diagram) and an example of Proxy Pattern. It has a few recommendations to follow when implementing the Proxy Patter. It also explains the subtle differences between Proxy, Decorator and Adapter pattern. It has simple code examples of Proxy Pattern in Java, C#, C++ and PHP. However, it does not have code examples of Proxy Pattern in Ruby.
