I would like to know if it is possible to configure the mikrotik proxy web cache (v-5.20) but behind a proxy .. in this case a squid.

Sure, there is field “Parent Proxy” so you can configure “Upstream proxy”
I think that is what you look for. Under the /ip proxy context

parent-proxy
(Ip4 | ip6; Default: 0.0.0.0) IP address and port of another HTTP proxy to redirect all requests to. If set to 0.0.0.0 parent proxy is not used.

parent-proxy-port (integer: 0..65535; Default: 0)
Port that parent proxy is listening on.
