Hello my good folks! I got something to share with you folks. Quite sometime ago, I mentioned a command-line switch for Chromium/Chrome - --host-rules- which would allow to map whatever domain/*.domain.com to localhost (127.0.0.1), map to specific ports, and even IP addresses. Moments ago, I was looking to restrict access by TLD (top level domain), such as *.com, *.net, etc. Well, guess what? --host-rules does accept TLDs! Example: "C:\Program Files\Chromium\chrome.exe" --host-rules="MAP *127.0.0.1", EXCLUDE *.com","MAP *127.0.0.1", EXCLUDE *.net" In the example above, I'm only allowing to connect to domains ending in those two TLDs. Quite useful to block certain TLDs, which are constantly seen as being serving malware, exploits... I hope this can serve you well!
