Hi, thx for response. I see the example. Its pretty interesting. Also another option I found in the documentation: http://mapserver.org/cgi/runsub.html
I see in the MS6.2 should be possible to act on DATA and DATAPATTERN. I guess this could be a good choice, but no other information on this and how to use. Is this runtime substitution for DATA and DATAPATTERN really available ?
