Hi,=20

could you please post the complete request-String. I guess there is no
mapextent set in the request so mapserver uses the mapextent in the
mapfile. You have to set the extents of your map everytime you request a
map also your just switching layers.=20

best regards
Oliver

Hi all,

I have managed to get the CGI Version of MapServer 4 to work being

I=92ve played with).=20
=20
All is working fine; I can zoom in/out pan etc=85 I now want to be able =
to
toggle layers on and off using &layers=3D but doing this always resets =
the
zoom level back to the initial extent in the .map file. Is this expected
behaviour, does changing the layers reload the .map, I don=92t want to
code around this if it is something I am doing wrong.
=20
Hope this makes sense.

Thanks in advance.
