This is most likely not due to WCCP but due to interception of http
traffic. WCCP is not at all involved on SSL requests, and neither is any
other interception method.

Many web sites dislike https:// requests coming from a different address
than the http:// requests initiating the session.

As https:// is not intercepted but routed like any other traffic the
requests arrives with the real client IP address.

To get around this you have three options

a) NAT the traffic outside the proxy and clients, making sure that both
intercepted and normally routed traffic uses the same source IP address.

b) Have the clients configured to use the proxy.

c) Add access lists to your intercepting routers to not intercept sites
where this is a problem.

Then something was seriously wrong in your WCCP setup.
