>From what I've seen and read, you don't write back HTML. You send back either text or XML that is parsed by the JS in the original page. That JS also updates the existing page. So, when you send a response back from your CGI program, you send it back out with the same concepts that we use for CGI, but the parsing work is the extra steps required in the JS. Bob Cozzi was supposed to write a follow on article to address the parsing side of it. I do not know if he has yet.
