I'm not sure if this is the correct place to post but I have some queries about WCCP which I'm not sure who to address to. If this is not the right place then can someone please point me in the right direction.
I'm writing a WCCP client and have found the RFC to be vague in some areas.
1] Does WCCP allow the caching device/wccp client to say "dear router, can you please only redirect traffic destined for ips X, Y and Z to me". I realize I can statically configure access lists on the router itself but I would like to use the WCCP protocol itself to "opt in" certain destinations for redirection. Is this possible? If it is not possible in the way I have outlined - is it possible in any form?
2] The WCCP protocol allows for the definition of a dynamic service group. I know squid supports these. However it seems that there is a finite list of ports that can be associated with a service group. Is there any way at all to have a service group associated with "all ports". I suspect this is possible but I don't know what form my "I_AM_HERE" message would take to communicate that. I have tried passing through all 8 ports as 0 but that seems to only result in nothing getting redirected to the web caching device.
