You have your iptables rules ordered wrong, and you're missing an http permit.

You have:

> -A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
> -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
> -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited

The above will reject anything else, and you'll never make it past there to get to your otherwise valid:

> -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

What you need is more like:

> -A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
> -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
> -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j
> -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j
> -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
