[mapserver-users] Re: Run-time Substitution and Raster file problem

[thomas bonfort]

as a rule of thumb, you should always use quotes around your strings.

the stars I was talking about come from your mapfile snippet:

DATA         *../grib/ds_vis%fhour%.grb*

with RTS, your queries will fail if you do not add a fhour= parameter
to your http query, as in that case %fhour% will not be replaced. you
can have a look at using default substitutions in the docs if you want
the fhour parameter to become optional.
