Is there way to keep objects alive?

[planb]

Hi!

Is there way to keep object alive when navigating around website? For example I would like to keep object "countries" so that I wouldn't need to fetch information every time from db.

Another thing related to previous one... Is it possible to create "main" class that is created once when user logs in and therefrom it calls other page objects without dying (reloading the page)?

Too much servlet-like thinking?

you can serialize objects and then pass them between pages. But in doing so you loose objects\'s methods.
Since serializing is quite cpu-demanding, I suggest that you pass only data not whole objects.
Therefore I don\'t see any usefullnes in using one main object. If you are after speed, žI think you should look at caching instead.
