Thank you for raising this. It depends on the application, so could you give us more information on that? What type of application is it? How is it hosted? (e.g., Is it behind a load balancer, VPN, or firewall?) How do you authenticate?
Have a look at these older answers that might help in your situation.
If that doesn't help, please provide more details on what you need to integrate to let you know our suggestions for that.
Thank you, and take care!
