[mapserver-users] Dynamic Reference Map

[Steve Lime]

Gabe: This is related to changes at the 5.0 release level limiting what can be changed via
URL. There has been a thread on this in the last couple of weeks or so. I'm going to be trying
to restore 5.0 capabilities but with security hobbles in place but that won't happen until 5.2.1
at the earliest and more likely 5.4 so for now you're out of luck unless you're in position to 
recompile.
