I've got some minor experience with php, but my question is:
How do I verify and display an alert when a link in my page is visited in http instead of https. I use canarytokens to display an image, to see where someone is coming from. But the page list 32 visits, but I only have 2 triggers of the canary token. Which brought me to the idea, how can i display a PopUp that the visitor is vulnerable to an ssl downgrade attack, suggesting to use https everywhere in order to keep the end users / visitors safe?
A sample page is: https://cyberawareonline.isee2it.nl/index.php/en/security/63-passwords
Would appreciate it if you could help me out.
Kind regards, Martijn
