Hi,
Sorry, I don't understand what is the different you mean by Client side
web caching and Server side web caching.
I think WCCP is always: Client --> Cache Engineer ---> Web Servers.
"In" means inbound traffic will be checked for redirection, and "Out"
means outbound traffic will be checked for redirection.
Am I misunderstand?
Best Regards,
William Chen
