Changing a layer's DATA via the URL in MapServer 5.0

[Jan Hartmann]

Yes, that did it, thanks Assefa, Steve. It actually said so in the CGI Reference Guide, with an example of the different calls for MapServer 4 and 5, so next time I'm going to read the manual completely to the end :-)

Note that I believe you also need to set DATAPATTERN to a regex to restrict what values DATA can take. This isn't new but is required.

   You could try something like
...&map.layer[plan]=data+amby/verzamelplan.tif

This seem to work.
