[mapserver-users] MAXSCALEDENOM using runtime var

[Scott]

Thanks for the response.

My mapserv binary is in a wrapper so I have control over dubious 
features I may (intentionally) introduce.

With that said, if it's not readily available and only available via 
modification, someone more knowledgeable had good reason. I'll think of 
a different approach.

Thanks again!
