Are you sure you want to use different directories here? Also check if
localhost is resolved the way you intend it to.

You probably receive an error message in some text mime type instead of
an image mime type. This cannot be parsed as an image -> unrecognized
image format.

Common mistake: you do. You call the WMS server and _always_ receive a
raster image. Just like when you call a 'classic' cgi MapServer with
mode=map. The type POLYGON should be RASTER. If you want to transfer
vectors over the net, you want to use WFS. But you don't have to, as
your WMS server always produces a raster map, no matter what sources it
is using.

You can hide the mapfile name completely, as described in the wms server
howto on the mapserver documentation pages.
