[Mapserver-users] wms and projections

[Charlton Purvis]

Hi, Amit:

I have found that the MIN/MAX SCALES don't necessarily match up
precisely between regular mapserver cgi calls and WMS calls.

So I'd play around w/ your MINSCALE since that made a difference w/ your
cgi results.  Make it something ridiculous to make sure it includes
everything.
