[mapserver-users] MapServer Environment Variables and IIS

[geographika]

Some further details after debugging. I modified mmaphttp.c and 
recompiled MapServer just to confirm the missing environment variables.

   // pszCurlCABundle = "C:\\MapServer\\bin\\curl\\curl-ca-bundle.crt"; 
// works when hardcoded
   pszCurlCABundle = getenv("Path");
   msDebug("Test CURL_CA_BUNDLE=%s\n", pszCurlCABundle);

   test1 = getenv("Path");
   msDebug("Path=%s\n", test1);

Then run using mapserv the env variables are correct. When run in IIS 
using FastCGI both appear as null in the log file.

[Tue Feb 10 13:54:13 2015].868000 Test CURL_CA_BUNDLE=(null)
[Tue Feb 10 13:54:13 2015].868000 Path=(null)

getenv is part of the standard C library 
http://www.codingunit.com/c-reference-stdlib-h-function-getenv
So I guess this must be an IIS/FastCGI issue rather than MapServer?
