How can I redirect HTTP traffic to an absolute link path with iptables?

Question

I'm trying to redirect a host to a specific link on my network when they try to browse through HTTP.

The IP address of the host I'm trying to redirect is 192.168.2.19 and my web-server is on 192.168.2.15:6969/test.js. When I redirect the user I can only get him to 192.168.2.15:6969 and not the relative path. I tried specifying in the iptables command but it did not work.

Here's what I did:

echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3000 iptables -t nat -A POSTROUTING -j MASQUERADE iptables -t nat -A PREROUTING -s 192.168.2.19 -p tcp --dport 80 -j DNAT --to-destination 192.168.2.15:3000/test.js

You cannot do this with iptables. You're trying to perform an HTTP redirect, so you'll need to perform the redirect using an application that speaks HTTP, like apache or nginx.
