setting apache environment variable

Question

Hi ,

My hosting environment using Server version: Apache/2.2.14 (Unix) and I am modifying ./usr/local/apache/conf/httpd.conf to set environment variable and restarting the server .

SetEnv XML-RPC-IPs 193.45.32.21

I did set it as a first entry in the file and restarted the server . But even restarting if I try to print it is still getting me black , Am I missing any thing ?

echo "My IP address ".$_SERVER['XML-RPC-IPs'];

Thanks for your help Regards Kiran
