Hi everyone,
Thanks for all the spirited discussion and suggestions. I am still
trying to digest all this, and get up to speed with JSON, proxies, etc
(and work on other projects). Unfortunately, my web host doesn't
support PHP on the server we use (Windows 2000 with IIS).
In response to Bratliff, I will say that I hope to build connections
to WFS data that are dynamically updated, so that I don't have to pay
attention to when updates have been made, how often, etc., so that I
know that my users always have the most current data.
Thanks again, when I figure something out, I will post a link to my
solution, but in the meantime, if anyone else has additional thoughts,
examples, I'd love to see them.
cheers,
Lara
