I need to know how to post information from an HTML <form> to a page that's within an IFRAME on an external server. In other words, the page with the <form> is on the first server, page being posted to is on the second server within an IFRAME which is also on the second server.
I've seen snippets of code for posting to a page within an IFRAME, but I believe that these apply to an IFRAME and target page on the same server as the posting page.
Any responses will be appreciated. This is my first time posting to this forum.
