Can i check if visitors are seeing older version of site?

[sk3pt1c]

We recently relaunched one of our sites where i work and we've had an issue of visitors accessing cached pages and not seeing the redesigned content.

Is there any way i can check if someone is visiting the cached page and tell them to reload?

Or force a reload on all pages or something like that?

It's crucial for this to happen cause we've had visitors send contact form data from older forms and we've had buggy data because we've updated for the new forms.

Thanks
