reading a past thread started by me, I realize that I should have
learned how to implement Philip's advice on using stateless
continuations, but well I didn't. So I still use vanilla
`send/suspend/dispatch` and hence my users hit the "Sorry, this page
has expired. Please go back." The quick fix is to tell them that they
should go to page xyz.com. But I don't know how I can easily change
this error message to add a link. Anyone?
I'm about to leave for travel or else I would have done some digging
around.
PS: For some reason I keep hitting these errors faster than in the
past - as in, within a few minutes. Any idea why that might be and how
to increase the time? I can crank up the RAM of the machine too,
anything that cuts down on developer time really. I'll be back in the
new year to actually fix this, but not now.
Did you perhaps change the continuation manager - or its setup?

As to where to put your message: you can install a custom "expiration"
handler in the continuation manager. Unfortunately I haven't done this
in a very long time, so I can't guide you through it. Perhaps someone
(Jay?) knows exactly what to do.
