You can use wildcards in URL category exception lists to easily configure a
single entry to match to multiple website subdomains and pages, without having
to specify exact subdomains and pages.
Follow these guidelines when creating wildcard entries:
The following characters are considered token separators: . / ? & = ;
+
Every string separated by one or two of these characters is a token. Use
wildcard characters as token placeholders, indicating that a specific
token can contain any value.
In place of a token, use either an asterisk (*) or a caret (^) to
indicate a wildcard value.
Wildcard characters must be the only character within a token. For
example, www.gmail*.com would be invalid because the asterisk follows
other characters. An entry can contain multiple wildcards, however.
