[mapserver-users] CGI variable "map" fails to validate.

[David Pavlíček]

Hi Steve,
your pattern works like a charm... escaped hyphen was the issue. I tested
the previous regex with regex101.com and it matches with no problems
against most of the available variants except PCRE. Which regex engine is
suitable for a test against MapServer?

Thank you.
