URL patterns use an extremely simple syntax. Every character in a pattern must match the corresponding character in the URL path exactly, with two exceptions. At the end of a pattern, /* matches any sequence of characters from that point forward. The pattern *.extension matches any file name ending with extension. No other wildcards are supported, and an asterisk at any other position in the pattern is not a wildcard. First, the container prefers an exact path match over a wildcard path match. Second, the container prefers to match the longest pattern. Third, the container prefers path matches over filetype matches. Finally, the pattern <url-pattern>/</url-pattern> always matches any request that no other pattern matches
