[mapguide-users] render service

[Andy Morsell]

That solution does not apply to the tile cache - only to the AJAX viewer
generated map.  There is an RFC in the works that will allow you to
designate the tile cache format as PNG or JPG.

hi Andy!

I try yours solution but in TileCache (after delete it before) MGOS still
generate PNG files.
