MapServer & IWS 8.0 : Connectiontype WMS

[Fabio D'Ovidio]

Hi!
I have a problem with mapserver 4.8.3 connectiontype WMS to IWS 8.0 (Image Web Server 
8.0) on Windows Server 2003 and IIS 6.0

When I set in the layer object this connection :

CONNECTIONTYPE WMS 
CONNECTION 
"http://myserver/ecwp/ecw_wms.dll?REQUEST=Getmap&VERSION=1.1.0&SERVICE=WM
S&layers=SUD_PUGLIA&styles=&SRS=EPSG:4326&format=image/png"

the characters "." and "," are trasformed in ASCII Hex code and so the BBOX (that i pass to 
mapserver request) changes from :

BBOX=14.696444805187044,39.710853059558424,18.889601564329261,42.33017784967
0967

to :

BBOX=14%2E6990953467541%2C39%2E7137634204363%2C18%2E8869510227622%2
C42%2E3272674887931

What can I do ?

Thanks
