Here is my apache configuration file.
I have two 
domain names running on same ip but i want them to point to different webapps. But in this case both point to the one intended for e-yantra.org.
If I copy paste akshar.co.in part before E-yantra.org both start pointing to akshar.co.in
I have two A DNS entries (one per 
domain name) pointing to the same IP.
