How to Whitelist URLs with specific keywords?

The initial `*` is a syntax error, probably you meant to put a space before that? — tripleee, Jan 14 '20 at 13:51

Hello Hian - i am not sure why links are not working when I add the Regex URL pattern. Please check initial post I just updated – user3618585 Jan 14 '20 at 13:43
`/ *= *Xqv79DCBYJo&/g` add a space after / before *= – Hian Jan 14 '20 at 14:16

Try these as separate entries (at the same time):

For when your affiliate is the last entry in the URL:

^https://.*=Xqv79DCBYJo$

For when your affiliate is the somewhere in the middle of the URL:

^https://.*=Xqv79DCBYJo&.*$

These regular expressions use RE2 syntax which is a very basic regex implementation. Many common idioms such as "/g" do not work for these. See the syntax reference for details.

Fantastics!!! I used the second entry and it s working great!! Thank you. Question - Do you belive it's a good practice to whitelist URLs from affiliates? Those short links are posted on social media. – user3618585 Jan 14 '20 at 18:19
Personally I'd be whitelisting the top-level domains along with the affiliate ID. e.g. `^https://some.example.com/.*=Xqv79DCBYJo&.*$` – samthecodingman Jan 14 '20 at 18:37
I just followed your recommendation and it s working great. Thank you again! – user3618585 Jan 14 '20 at 19:38
I actually haven't yet used dynamic links so I wouldn't know. The best practice is to always tighten up your security rather than leave holes that can be exploited. If you can tighten up the security without sacrificing the functionality you desire, you should do so. – samthecodingman Jan 15 '20 at 20:59
I appreciate your input. Thank you very much – user3618585 Jan 17 '20 at 03:55
