[mapserver-users] Skipping layers that fail to load

[Stephen Woodbridge]

And building mapserver with the ./configure --ignore-missing-data does 
not solve this problem? I personally would prefer that these kind of 
options reside in the mapfile so you don't have to rebuild mapserver to 
turn them on when you forget.

Maybe we need something like:

MAP
   CONFIGURE
     IGNORE_MISSING_DATA ON
     IGNORE_BROKEN_LAYERS ON
     ...
   END

   ...
END

I think we already have something similar to this but I forget off the 
top of my head what the exact syntax is. Regardless of syntax, I do not 
think there is support currently for these options.

You might want to open a ticket after the discussion to document the 
thread and the request for an enhancement.
