[Mapserver-users] shape file reprojection on the fly.

[Pericles Nacionales]

Can of worms, I tell you... :)

When you say OGIS are you talking about WMS/WFS?  If so, that's where the
METADATA "wms_srs" parameter is for.  Specify the epsg codes for all
projections you want supported.  Perhaps the wms folks can confirm this?

See http://mapserver.gis.umn.edu/doc40/wms-server-howto.html for more
info.
