Hi!

Do following:

Make a form on the main WEB page that is hidden and contain only hidden elements. Assign values to send to server with command to these hidden elements of that form. When submitting, assign the URL to Action property of the form object, and assign also a TARGET value (or specify target using attribute for FORM element just in the page). That target should forward form submitting request to any other frame by ftrame name. This works the same way as for links - form results will be downloaded into the frame specified by the TARGET. I do not know though if IFRAME could be used as a TARGET for link and form, but you always can make a hidden frame insode of the main frameset with width or height = "0" and use that frame for dynamic data downloading.

HTH.
