Re: Rerouting http traffic without using routing protocol

There are many ways to make HTTP traffic go to a different destination, but it's usually called "proxying" or "redirecting", not "rerouting".

"Rerouting" has a specific meaning, but it applies at the IP level, so it affects a lot more than just http traffic.

So your question is just a tiny bit unclear.

If you want some HTTP traffic to go elsewhere, you could:

- modify the DNS record the clients are using to find the HTTP server, so that the clients will connect to some other server instead

- configure the target web server to send "redirect permanent" responses, pointing the clients to some other server instead

- set up a web proxy at the target IP address/port, and configure it to get the data from some other server

- set up an intercepting proxy (transparent proxy) and configure your clients' gateway to pass any outgoing HTTP traffic to the proxy instead, then use the proxy's configuration to decide what should happen to the traffic

... and many other things I don't know about.

What's your current situation like and what's the problem with it?

Re: Rerouting http traffic without using routing protocol

Hi Matti,

Your correct, redirecting is better.
Interception by a proxy as one of the options is one of the options I also talked about with the Windows boys.
The core switches configuration also needs some adjusting for working fail-over.

Re: Rerouting http traffic without using routing protocol

Hi Jaap,
I associate routing protocols for the need to dynamically update paths through the network.
Not to communicate wich way http traffic must go.

If you want your http traffic going another path than other traffic, then policy based routing may be an option to investigate?

Re: Rerouting http traffic without using routing protocol

Hallo Pieter,

That would be nice. However after searching, it's not a feature (just like route maps) that is 'included' in the software for the 6600's switches.
So I think I 'll have to stick with the internal proxy server to have http-traffic 'redirected' to WAN-connection I want it to go?
