Every ShoreComponent can contain attributes. The root component contains
special attribute called session cache. It’s a dictionary of URLs and
documents. When a component generates a picture, it remembers the URL
generated by Seaside and saves it with this picture into the session cache
under unique name. When the component wants to generate the picture again,
it takes only the URL from cache.
The problem is that it doesn’t work perfectly. Sometimes it switches the
pictures or doesn’t show the images at all. It’s interesting that the
frequency of cache failures sinks with every new user session.
