How to make correct iptable rule like browser port configuration - linux

Question

After searching the forums with no matching results, I asking hear.
I want to redirect every browser request in destination port 80 to another port (for example 8080). all in the localhost.
My workplace is linux, and I want to use the iptables rules and python code server.
The rule I used is:
iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to-port 8080.
I also tried some other flags like specific ip source and server etc.
The server listening on port 8080 is:
#!/usr/bin/env python
import SimpleHTTPServer
import SocketServer
def redirect_factory():
class RedirectServer(SimpleHTTPServer.SimpleHTTPRequestHandler):
def do_GET(self):
self.send_response(301)
self.send_header('Location', 'www.IdontCare.IdontKnow')
self.end_headers()
return RedirectServer
redirectServer = redirect_factory()
handler = SocketServer.TCPServer(('', 8080), redirectServer)
print("serving at port %s" % 8080)
handler.serve_forever()
The problem is that it works well when I configure my browser in the connection settings (without adding the iptables rules) like this:
But when I use the iptables rules it says that it have a broken pipe, and the browser request didn't received at all in the server. So if I write in the URL in the browser www.google.com I can't see it with the self.path value.
EDIT:
Here is the iptables -t nat -nvL --line-numbers output:
the rule is working, but it not done what I suppose.
I play a little with the rules, and if I put one of the next rules I can see in the CNAME in the self.headers value.
the rules is (I can just choose one of them):
iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to-port 80
iptables -t nat -A OUTPUT -p tcp --dport 80 -j DNAT --to-destination 127.0.0.1
If I not mistake, both of them done the same thing.
what am I do wrong ?
and how to make it work with iptables rules like the configuration of the browser?
Thanks!
