PowerHouse Web and 'states'

[Deskin, Bob]

The "ticket" is maintained by a memory-resident cookie that has a limited
life span. Could we do the same thing in PH Web? I suppose, but I don't see
that getting around the "statelessness" issue. If you're talking about
getting information back and forth, we can already do that. I'm sure we
could come up with slicker methods, but that's just technique. Even the
"tickets" don't really retain true state. There is still that separation
between browser and application.

Really we're getting philosophical here - Physical state versus Logical
state. Retaining Logical state isn't a problem as long as the state
description is available. Retaining physical state implies retaining buffers
and file pointers and being able to keep a relational transaction open while
the user is entering data. That PH Web doesn't do and for good reasons. In
fact very few web applications do that sort of thing because the user can
walk away at any time. And if they do, you've got to clean up the pending
transactions.

Or am I missing a point?

G'day Bob, et. al. at Cognos

The 'other' Cognos web tools (IWR, PPW, etc.) use a 'ticket' maintained by
the web server to track the user state of a HTML form.  Why can't you use
something similar to get around the 'stateless' limitations in PH Web?

Another thought: why couldn't a cookie be used to the same effect?
