Hi Steve,
regardless of the projection settings, I get the following result:
For
http://localhost//cgi-bin/ows?map=mapfile&mode=itemnquery&qlayer=typ&qitem=zver&qstring=2
I see
msLoadMap(): Regular expression error. MS_DEFAULT_MAPFILE_PATTERN
validation failed. msEvalRegex(): Regular expression error. String
failed expression test.
And for
http://localhost//cgi-bin/ows?mode=itemnquery&qlayer=typ&qitem=zver&qstring=2
I see
mapserv(): Web application error. Parameter 'qstring' value fails to
validate. msValidateParameter(): Regular expression error. Parameter
pattern validation failed.
Cheers,
Michal
