Agree, the commentor is hung up on their demonstrably superior understanding of HTTP. We found at least one scanning service to be fetching the URL with the user agent of a browser, and executing JavaScript on the page. A lot of our user interactions could be simpler, but this sort of behaviour led to many things being put behind a "go" button. I only wonder how long before scanners and search engines start clicking these buttons to activate content on the page so they can scan/index it.
