Hi there, Here is my problem: Web site is served from domain A (an IIS web server) Web site uses a plugin JavaScript component from web site B (a Zope web server) which is plugged into a page served by A (not a frame of it's own). Web site JavaScript plugin opens a new window, creates a form, fills the form vars and posts it to Zope at B (the plugin uses this method to communicate with Zope Server) Zope web site returns a newly created page with the response to the JavaScript's request entered in a form var. JavaScript plugin must now access the form var to extract the answer. This does not work (access denied error) as the JavaScript plugin in page served from A cannot access elements in page served from B. Is there a way that I can set the headers/whatever of the page served by Zope so that it seems as if it was served by A and not by B? (I know how to get A's domain from HTTP_REFERER, but does not know how to set the headers/whatever). I wouldn't be surprised if this is totally impossible (but am REALLY hoping it is!). B.t.w. the audience is mostly I.E. browsers - I don't know if this is browser dependent though. Thanks Etienne.
