I have a web application deployed on tomcat on linux ,,,now this application is trying to speak to internet but server is behind a proxy server

Application doesnt understand proxy I want to redirect all the http traffic this server is generating to this proxy server

I understand using IP tables might be an option but I am new to this and tried may conbiations which have failed

iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 125.236.71.228:8080
iptables -t nat -A PREROUTING -p tcp --dport 443 -j DNAT --to-destination 125.236.71.228:8080

I tried replacing PRE ROUTING With OUTPUT as well...but to no sucess :'(

Hello,

you have to set-up your proxy server as reverse proxy and your HTTP server with mod_proxy.
