I am having an issue with Mapserver 6.4.1 when attempting to pass a
layer labelitem parameter setting via URL.
The map file contains the following validation for layer 0
VALIDATION
labelitem [a-z]+
END
The following request works (ignore the double quotes around the entire
URL):
the + sign is used to encode a space in a url, and that space is what
mapserver's parser is looking for. translated to mapfile syntax, your
first two requests are parsed as
labelitem columnname
whereas the last one is
labelitem+columnname
which is invalid.
tl;dr don't escape the + sign,
-users] Mapserver CGI URL parameter parsing with plus
character escaped as %2b

Thank you for the speedy response.
Yes.. that was exactly the issue. By placing a literal space within the
parameter within OpenLayers, the URL arrives at mapserver escaped as
labelitem%20columnname and everything works.
May I suggest somewhere in the Mapserver CGI documentation it might
mention
