IdP access to server environment variables

[Liam Hoekenga]

I find myself asking a question that I asked a couple of years ago.

I'd like to access some environment variables set by our SSO for use  
in our IdP configuration.

We're using mod_proxy and mod_proxy_ajp.  I know that mod_proxy_ajp  
will forward any environment variable with the AJP_ prefix to tomcat.   
Is it then possible to access them?  (Maybe  
$requestContext.getAttribute("variableName")?)
