WCCP redirections over IPv6

Hi,

I've a question related to WCCP and IPv6.

Let's imagine a web-cache cluster, all the nodes dual stack (IPv4+IPv6) and all of them supporting WCCP (also IPv4+IPv6) for transparent web-cache, so they can cache either IPv6 or IPv4 web pages.

Let's imagine one Cisco router that is also dual-stack and having WCCP support (AFAIK only for IPv4). I assume that the router and the web-cache nodes are able to communicate to each other through either IPv6 and/or IPv4 for any protocol different than WCCP. For WCCP only communication through IPv4 is feasible (IPv4 only support for WCC in the cisco router).

My question is what about the port-80 IPv6 traffic (http queries indeed) forwarded to the router from the user's hosts?

Would such a traffic be forwarded to the external IPv6 HTTP public server (like no-http traffic)?

Would such a traffic be forwarded to the web-cache farm (like IPv4-http traffic does) in spite of WCCP supports only IPv4?

In other words, the IPv4-only-WCCP capable cisco router (but dual-stack) inspects only the IPv4 packets looking for the TCP-80 port or it does it also for IPv6 packets?

Regards

Miguel
