For that you will need the list of domains to be in some dynamically 
generated database. Along with a content adaptation module (may or may 
not be available publicly) to parse and process all HTML going through 
the proxy that updates your database. Maybe also TLS decryption of 
traffic so it can be passed to the adapter.

You can in some situations check the Referer header URLs against your 
whitelist. But that is not available on TLS traffic, unpredictable 
whether Referer even arrives on non-TLS and can be easily forged by 
clients to bypass proxy rules.
