You can avoid lots of unnecessary state-saving by judicious use of WASH's 'once' function. eg.
Hmm. I have tried this, but I'm not seeing any change in the amount of saved state as a result of using once. For instance, I have a selection screen. People can select things there, then go off and do things. At various points, the user could realize they made the wrong selection, so I call the selection screen again. However, even though I have once $ standardQuery $ ... in the selection screen, all that state is saved... I don't think I can use forever there either, because I'm using that trick (which does seem to work) to enable returning to a yet earlier page. Maybe I'm missing what once does. Thanks again for your help. -- John
