I would like to implement reCAPTCHA either to a link or a page designated specifically for the tool. Instead of having CAPTCHA in a form widget, I want it to appear when a user clicks a link. This is similar to password protection for a page, but I don't want a designated password. I just want a user to be prompted to solve the CAPTCHA challenge before being redirected to a link's destination. For example: A user wants to see a page that contains protected content, they click the link to that page and are prompted with CAPTCHA and must solve this before the page loads. Is this possible to do without a form widget?
