Users PayPal recurring payments not being canceled when they unsubscribe on the site

I have seen other threads on the same issue ...

This is what has been recommended -

"FYI with paypal standard payments (which Membership uses), you cannot programattically cancel a subscription. The best you can to is make a button that links to paypal, so that after you click it and login it will search for a subscription tied to the email in the link."

Can you please explain how linking directly to paypal (as recommended in the other thread) would affect the status of the subscription on our site. Will cancelling in paypal auto reflect the cancellation of the subscription for the user on our site?

if yes, can you provide an example of the link/url we need to use to set this up.
