Matches parameters ending with
the keyword
It can be present once at the end of
a filtering entry.
& Stands for one valid character
It can be present multiple times at
any position of a filtering entry,
consecutively or inconsecutively,
and cannot be used next to an
asterisk (*). If it is present at the
beginning or end of a filtering
entry, it must be next to a caret (^)
or a dollar sign ($).
*
Stands for up to 4 valid characters
including spaces
It can be present once in the middle
of a filtering entry.
When using the wildcards, also follow the principles below:
• A filtering entry with a caret (^) at the beginning or a dollar sign ($) at the end indicates an exact
match. For example, filtering entry ^webfilter$ matches website addresses containing standalone
webfilter, like www.abc.com/webfilter any. It does not match website addresses like
www.abc.com/webfilterany.
• A filtering entry with neither a caret (^) at the beginning nor a dollar sign ($) at the end indicates
a fuzzy match, and matches website addresses containing the keyword.
