How to setup page cache not to cache regirstration page

Hello guys. I would like to setup w3 total cache plugin not to cache registration page. the url of my register page is https://www.mydomain.com/register I have tried adding /register and /register/ under never cache the following pages but it didnt work…

The register page has got password strength indicator which doesnt work when this plugin is installed which I think it is caused by page cache.

Is there anyone who can help me with this?
