Man I had hoped that if my name was going to be used for something it'd
be for good. That hope has been shattered.
I had to educate myself as to what "Warnocked" means to ensure that I
was not in some means being implicated here. *sigh* I'm now an innocent
pariah.

I really hope the silence isn't an indication that the question is too
stupid. Getting blank images instead of an error message is actually a
big problem with my server configuration, as I'm caching all responses
with an image/* content-type.

In my mapfile, I have several layers with connectiontype WMS. Once in
a while, the WMS-servers that deliver these layers will fail, usually
due to high load, and return an application/vnd.ogc.se_xml
exception. In these cases, I'd like mapserver to return an exception
as well, but instead, mapserver will just log the error message in
MS_ERRORFILE, and continue drawing the rest of the layers. If there
are no more layers, it will result in a blank image.
(BTW: I've also noticed the same behaviour if the remote wms-server
answers with an internal server error)
Here's the layer definition that I use for testing. exception.cgi will
always return a dummy XML exception.
LAYER
NAME "exception"
TYPE RASTER
STATUS ON
CONNECTION "http://wms1.oslo.dnmi.no/cgi-bin/exception.cgi"
CONNECTIONTYPE WMS
OFFSITE 255 255 254
METADATA
"wms_srs" "EPSG:4326"
"wms_name" "exception"
"wms_server_version" "1.1.1"
"wms_formatlist" "image/png"
"wms_format" "image/png"
"wms_exceptions_format" "application/vnd.ogc.se_xml"
END #metadata
END #layer
Is there something I can do to force mapserver to fail, and return an
exception if it fails to draw any of the wms-layers?
I'm using mapserver 4.10
