The hostname validation incorrectly requires a letter in each segment of FQDN (it could not be comprised of only digits). However, FQDNs may contain any combination of letters, digits, and hyphens in each segment.
The request is blocked due to an “Illegal parameter data type” violation.
- Illegal parameter data type enabled - Add parameter as 'uri' data-type - Send a request configured with uri data-type parameter as a value, such as "abc.123.co.in.us:80" with segments containing only digits.
None
The request passes with no violations.
