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

[Steve Lime]

Hi David: Presumably the Docker image is running the most recent version of
7.4 which would have that pull request applied. That said, I don't think
it's the culprit here and I have seen some issues with -'s where the
MS_MAP_PATTERN expression compiles fine but doesn't match as expected.
Re-writing the expression to move the - character can help. Try this:


MS_MAP_PATTERN=^\/etc\/mapserver\/([^\.][-_A-Za-z0-9\.]+\/{1})*([-_A-Za-z0-9\.]+\.map)$
