WebSEAL supports wildcard pattern matching characters.
| Character | Description |
|---|---|
| \ | The character that follows the backslash is part of a special sequence. For example, \t is the TAB character. Can be used to escape the other pattern matching characters: ( ? * [ ] ^ ). To match the backslash character, use \\. |
| ? | Wildcard that matches a single character. For example, the string abcde is matched by the expression ab?de |
| * | Wildcard that matches zero or more characters. |
| [] | Defines a set of characters, from which any can match. For example, the string abcde is matched with the regular expression ab[cty]de. |
| ^ | Indicates a negation. For example, the expression [^ab] matches anything but the a or b characters. |
