I am trying to develop a web based interface to automation equipment (Allen Bradley plc's in this case) to use for an operator interface. I am using SVG to develop graphics and want to use javascript to manipulate the graphics based on data from the plc. I am looking for a way to pull more data from the server without having to reload the page. My question is will XML-RPC allow this. Or does Zope have some other mechanism that would allow this. Thanks for any help.
Actually this is mainly a client-side problem, on server side you have total freedom to serve any protocol ;) Often this kind of problem is solved by having twho frames and data is aquired by reloading the "data-page" which then manipulates the "presentation-page" using javascript, possibly in its onLoad method. ------------ Hannu
