I had already formulated an entry recently in which I asked for the error message "msCGILoadMap (): Web application error. CGI variable" map "is not set." asked.
Now I think I have found a more accurate diagnosis. For our project we need several mapserv.exe, because we present different maps to different users (Mapfiles). Every time I come up with a new copy of the mapserv.exe this error message follows. Does anyone know this problem? Does something have to be considered when copying the file?
