> The ICP implementation in Traffic Server broke when epoll() was introduced.  Its still an interesting and used feature in caches:
> - when a caching layer of several boxes are used ICP helps to reduce disparities when a client is not routed to the same cache on subsequent requests
> - after a restart, it can help reduce the time spent in a cold cache situation
