Hi T.J.,
Thanks for your response.Your suggestion of updating the body element
does almost what I want, but it will disrupt the way the browser's
back button work since the operation will be a page element update
instead of a new pageload.
What do you mean by "I don't think branching on the result really
argues this either for or against Ajax.Request."?
My understanding is that Ajax.Request renders a new webpage using the
server response, whereas Ajax.Updater updates page elements.
Are you suggesting that it's possible to 1) Get data from server, 2)
parse the data (see if has an http header), and then 3) call a
separate operation that will render an element or render a new page?
If so, how would I do that?
Thanks
Alex
