[Chameleon] question about session map file

[He, Matt Yubin]

Hi All:

            

            I am using the WMSBrowser widget to add layer. I modified
this widget to add group name into the new layer. 

I also modified legend_Template file to group all layers based on their
group name (please see below).

However, when I added a new layer, in the session map file
(C:/ms4w/tmp/sess_[session_id]/[unique_id].map), there are two identical
layers added.  I am trying to figure out why two layers were added into
session map file instead of one. 

 

Could some one tell me: 1. how session map file was generated? Is it by
Chameleon, or by Mapserver code, or by MS4W code?

2. is MS4W code open source? There are some dll files, where to get
source?

 

Thank you very much.

 

Matt
