Projection on mapserver WMS versus cgi-bin

[Sandro Danilo Gatto]

Hello

I've been making some tests with mapserver 4.4.1 as a
WMS server and I came across a strange behavior (at
least, from my point of view).

I get a blank image if I type the following URL:
http://localhost/cgi-bin/mapserv441.exe?service=wms&version=1.1.1&request=getmap&map=C:\Arquivos%20de%20programas\Apache%20Group\Apache2\htdocs\sigppt\wms.map&layers=area_edificada

Well, the problem is: I get a perfect image, with all
the data I want, if I type
http://localhost/cgi-bin/mapserv441.exe?mode=map&map=C:\Arquivos%20de%20programas\Apache%20Group\Apache2\htdocs\sigppt\wms.map&layer=area_edificada

It works if I use project as

PROJECTION
   "init=epsg:29118"
END

instead of 29100, but the images returned by wms and
cgi-bin are different (wms returns a "wider" image).

Note that the map file is exactly the same and that
both URL work perfect if Mapserver is version 4.0.1.

Could somebody tell me what I'm doing wrong?


Thanks to all


Sandro
