[mapserver-users] MapServer Environment Variables and IIS

[geographika]

Thanks Jeff.
The environment variable is definitely set in system variables, and I've 
rebooted a few times now. It also happens on both a w08r2 server and a 
Windows 7 machine.
I can see it in 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session 
Manager\Environment
I'm using x64 MapServer, but the environment variables appear in my x64 
Python script.
I had this working a couple of years ago, and tried to see if anything 
has changed in the MS source since but no luck.

I think I should also be able to set it in the web.config using the 
following, but also no luck:

         <fastCgi>
             <application fullPath="C:\Mapserver\bin\mapserv.exe">
                 <environmentVariables>
                     <environmentVariable name="CURL_CA_BUNDLE" 
value="C:\Mapserver\bin\curl\curl-ca-bundle.crt" />
                 </environmentVariables>
             </application>
         </fastCgi>

Regards,

Seth
