Clarification : Subdomain blocking

[theapache64]

So when I say block netflix.com, does it block all these subdomains? 🤔

selfcontrol/Block Management/BlockManager.m

Lines 332 to 335 in 7d350da

	if ([hostName hasSuffix: @"netflix.com"]) {
	[newHosts addObject: @"assets.nflxext.com"];
	[newHosts addObject: @"codex.nflxext.com"];
	[newHosts addObject: @"nflxext.com"];

Yep! If you don't want that behavior, turn off the "block common subdomains" setting

Here's my settings

and here's my block list

and here's my /etc/host file after the timer.

# END SELFCONTROL BLOCK

I've asked the SCA to block twitter.com, it also blocked api.twitter.com as expected. I've also asked to block netflix.com but it didn't block the netflix sub domains. any idea why?

[cstigler]

Hm, not sure on that one. But as a workaround, you can always just add those domains to your list manually.

Just curious, is it possible to use wildcards? Like, I uncheck "Block common subdomains", but if for a certain domain I want to block the main domain and all subdomains, to set something like *.facebook.com instead of adding every subdomain for facebook.com
