Multiple URL for EBS

We have three node apps and two node DB [RAC]

hostapp1.abc.com:8001

hostapp2.abc.com:8001

hostapp3.abc.com:8001

Load Balance URL ebus.abc.com:80

We want to URL to work individually and with Load Balancer

ie.

http://hostapp1.abc.com:8001 should also work without redirecting to Load Balancer URL

http://hostapp2.abc.com:8001 should also work without redirecting to Load Balancer URL

http://hostapp3.abc.com:8001 should also work without redirecting to Load Balancer URL

http://ebus.abc.com:80  Load Balancer URL also working

so that means we want to have 4 URLs working for EBS . 3 individual host URLs and 1 Load Balancer URL
