clear cache after log in WP

Hello, fisrt of all thank you for best cache plugin.
But i have one question. We are using it on eshop with wholesale roles. Is there any way how to clear users cache when he logs in?

Because if he browse eshop as not logged he sees retail prices, but after he logs in he should see wholesale prices. But on product he visited before as not logged he sees retail prices even if he is logged in
thank you for any help
