Hm, that's odd.  Static resources (like images and stylesheets) are
given unique URLs separate from any session - they are, in fact,
registered at the same level as sessions are, as WADocumentHandler
instances, in the WAApplication registry.  If you're getting an expiry
message, that means that they've been removed from that registry - but
this should only happen if the #isActive method of the handler returns
false, and unlike for WASession which will return false after a
certain period of inactivity, WADocumentHandler>>isActive *always*
returns true (which means, incidentally, that you have a very slow
memory leak if you keep changing stylesheets, because all of the old
ones will still be accessible).

Hopefully that description will help you somewhat to track this down...
