Mikrotik OS + Proxy, how to redirect some sites to a proxy?

Question

Mikrotik

There is a proxy server on the network, you need to configure Mikrotik OS so that it redirects to a proxy server that is connected to another provider. 2 providers, one in Mikrotik, the second in a proxy server.
The site xxx.xx is accessed from the Mikrotik network, Mikrotik looks at the list of sites in the list and makes a redirect through a proxy.
How to implement correctly?
It is desirable to autocomplete the list if there is a stub in the answer. :(
