Could anybody help me to understand the concept

[cookman]

What does the javadoc really mean?

"A module implements this interface when it needs to handle it before the operation is called on the target."

What's the relationship between a Module (CoreModule, BlockModule) and a Handler?

I'm confused:(

Thanks in advance!

[julien1]

this is related to the chain handling during the request. before being dispatched to the target the request can be handled by the module :

HTTP Request -> Nukes Servlet -> Chain of handlers -> Target module

so it has the chance to intercept the request and provide some kind of work, for instance the User module makes sure that if a user is using the site with the "remember me" token it is automatically authenticated.
