Custom filter rule: question

[lencc]

I would like to clarify filter rule behaviour in adblockers. If there is a filter, such as:
||twitter.com^

Will this rule also block domains, such as:
||platform.twitter.com^

[intense]

yes.

see
https://adblockplus.org/en/filter-cheatsheet
https://adblockplus.org/en/filters

example:

||ads.example.com^
This rule blocks:

http://ads.example.com/foo.gif
http://server1.ads.example.com/foo.gif
https://ads.example.com:8000/

This rule doesn't block:

http://ads.example.com.ua/foo.gif
http://example.com/redirect/http://ads.example.com/

Thank you!
