[Zope] How to make a trigger handler on moved object

Hello, I want to make method that as a handler when some content is moved to a new location. I want to capture another event, like deleted content, access and modify the content's title, etc. Inside the handler method/function/procedure, it will create a connection to another host. Anybody know how to make this happen? Any sample or tutorial will be great. Once more, I'm using Plone 2.5.2. Thank you. Regards, -jay-
