Does TS can work with ICP( Internet Cache Protocol)

[ChangCheng]

Hi guys:As we konw, ICP is a Web caching protocol used to exchange hints about 
the existence of URLs in neighbor caches. Caches exchange ICP queries and 
replies to gather information to use in selecting the most appropriate location 
from which to retrieve an object. 
I would like to konw does TS implement ICP ? or does it needa a plug-in to 
support ICP?
Thanks
