How to determine if page refreshed

[Jeevan Bihari <je...@yahoo.com>]

  Is there a method or some other indicator that gets called/set eclusively on a page refresh ?
Basically, one of the listeners on my page does a database query and I would like to avoid doing
that query if the user has refreshed the page.

Thanks,
Jeevan

The problem is that one request pretty much looks like another request to Tapestry, it can't tell
the difference.

WebObjects builds a unique id in to every URL it creates to handle this problem (I believe; it's
been a few years since I've seen a WO app).  I've been thinking that Tapestry may need to do the
same, to help with this case, and with duplicated form submissions.  I think that may wait for
release 3.1.
