[Seaside] A session-aware kind of FileLibrary - how/where to start

[Sven Van Caekenberghe]

Hi Joachim,

I would try to look at WAFileHandler, which is responsible for serving the files.

It seems to delegate most work to WAFileLibrary>>#handle:

Maybe you can subclass WAFileLibrary (insert your superclass before your concrete class) to check the session for a login.

Unfortunately, neither aRequestContext nor self return a WASession, although I entered _s and _k form a logged in session into the address bar of my Browser. This may be a naive approach, but as a fist test case this seemed like a good idea ;-)

Is subclassing WARequestHandler the wrong idea anyways? (I started my experiments with a subclass of WAFileLibrary, but that also didn't get me anywhere...).
