Add config file-level error redirection capability. about mapserver HOT 4 CLOSED

Currently one can set the ERROR attribute in an individual mapfile.

I have never before met this error redirection. Is it documented somewhere, and are there usage examples?

Oh, I have only used WMS/WFS/WCS and I think that during these 18 years I have never had anything else than METADATA in WEB. Never too late to learn more.

With a WMS mapfile it seems to be possible to show something else instead of
"mapserv(): Web application error. Traditional BROWSE mode requires a TEMPLATE in the WEB section, but none was provided" when the request is not even an erroneous WMS request. I feel relieved, our users have not lost much because of my ignorance.

Correct. Any errors associated with mapfile loading can't be redirected though unless there's something configured some other way and this would do it. Note that you can also disable all other native modes using something like this in the WEB metadata.

    METADATA
      ...
      ms_enable_modes "!*" # OGC services only
    END
