Hello,
We are facing a strange issue on haproxy server on our production
environment.
In DNS we point our domains/subdomains to haproxy using a cname. Our
servers are hosted on AWS.
For example, we have two subdomain pointing to haproxy.
subdomain.domain.com points to some.eip.on.aws..com
test.subdomain.domain.com points to some.eip.on.aws..com

Haproxy Version: HA-Proxy version 1.5.2 (haproxy-1.5.2-2.5.amzn1.x86_64)
OS: Amazon Linux AMI release 2014.03
Note: This is the latest version available on AWS.
Both the subdomain has different web pages. Now if we enter
test.subdomain.domain.com in the browser it goes into subdomain.domain.com
backend. We have no idea what is causing this issue.
Could you please help me solve this problem?
Additional Info:
Also we have exact same Haproxy config on QA and UAT environment and works
fine.
QA Environment:
Haproxy Version: HA-Proxy version 1.5.4
OS Version: CentOS release 6.3 (Final)
UAT Environment:
Haproxy Version: HA-Proxy version 1.3.26
OS Version: CentOS release 5.6 (Final)
