Dynamics 365 Claim Based With ADFS Logout and Back Button Issue

Hello Guys , 

I'm using Dynamics 365 on premise with ADFS claim based internally ( no IFD applied)

the sign out button redirected to ADFS successfully , but when I click back button or open the CRM url it redirects me to the CRM main page without any authentication required although I've already signed out.

How can I fix it ??

Thanks
