[Chameleon] question about session map file

[Julien-Samuel Lacroix]

Hi,
I'm not sure what you changed, but the WMSBrowser normally only add one 
layer, not two. You may try to review your changes.

Now to answer to your questions:
1. The session is created by Chameleon. The software has it's own 
session handling. For the mapfile, it is created by MapScript. The code 
is in the wrapper:
chameleon/htdocs/common/wrappers/map_session.php
The code is simply doing a $oMap->save(); soif you have two layers, it 
is probably because you added two of them in the map object in your code.

2. MS4W is only a package to easily install MapServer and related 
products. It does not really contains code by itself. The dll files 
comes from the various MapServer dependancy, not from MS4W itself.
