I am trying to implement a shopping cart. When the user clicks the
checkout button, 2 things need to be done. 1)Saving the user's data
and 2) open the checkout webpage (3rd party).
the checkout webpage requires a HTTP POST, so I cannot load my page
first, then redirect.
But maybe I can do this in a Google way. When I write an e-mail in
gmail, it saves the draft automatically. how is it done? I guess it
silently submits a form in the background. anyone has more information?
