That is a very interesting option. I hadn't realized how useful the
Post servlet was.

When I want to aggregate the data back together again, I can obviously
write a JSP page to do it, but is there a mechanism already in place?
For example if I post the JSON fragment I gave earlier, I would quite
like to get the same fragment back at the root address.

Thanks again
