Also remember, proxy will not work with HTTPS.

I can’t use web proxy… I have an external Cache

why you can’t use web proxy.

I have a special rules for traffic data between mikrotik & external cache…

look man you can do it through ur own proxy server, and you can do it through mikrotik webPROXY

through ur proxy server if you need to block downloading .biz
you can go to ur own proxy panel and block this path *.biz

through MIKROTIK WebPROXY you can do it by doing this steps:

1- Firewall > NAT > create new rule > chain: dstnat, protocol: 6 (tcp), dst-port: 80 > action: redirect to-ports:8080 .
2- IP> Web Proxy> Enable ( Check Mark On Enable ) > Port: 8080 > Access > Add New Rule > Path: *.biz > Action: Deny.

Good Luck
