[CentOS] redirecting web requests from localhost

[diegors at gmail.com]

IF (IF) is trying to get data by hostname, dnsmasq maybe could help. 
IF (IF) is by ip addres, problem still here. 

First he need understand how is working the app or wait to developer. 

I prefer lost 2 minutes with grep, that a lot of minutes with dnsmasq AND 2 minutes with grep later..

if a application makes a DNS request then it
asks DNS and not /etc/hosts - period

yum install dnsmasq
man dnsmasq

learn basics, see above

the application is not interested in /etc/hosts - why?
because /etc/hosts doesn't support record types like MX, TXT, SRV, SPF....
