Custom URL Categories are not Matching Correctly when URL Overlaps with Another Custom Category
Configurations with custom URL categories that match the same URLs can cause unpredictable results. With multiple custom URL categories that have overlapping regexes the URL will match multiple categories and an incorrect category may be chosen causing the wrong security policy to be used.
Custom category URLs should not overlap with other custom categories. Regex patterns should be constructed so that only one category can match a given URL request.
