[MapServer-users] How to add templates(html) to be use with getFeatureInfo for raster data

Fri Mar 24 13:49:40 PDT 2023

Thanks

I have already tried all kind of options with template and filenames.
What I was missing was the query option "info_format=text/html" doing 
eg. curl.

So my setup was working all the time, but my test curl was wrong.

Trygve
