The URL that usually define like trusted sites which user will going direct to Internet instead going to Zscaler or due to geolocation restriction the sites do not support according to that particular location, so user need to send traffic to other nodes.

shExpMatch("https://digi.com.my",
            ".*/digi/.*")

Using dnsDomainIs Arguments
