WCCP is generally preferred due to its "resiliency" in case 
a cache server becomes unavailable.

PBR works too but has no knowledge of the state of the cache 
server. It's great for testing though, as WCCP (from the 
time I played with it) was not particularly consistent re: 
stability between various trains or train revisions.

Things could have changed now, though. The network I play 
with now can't support caching due to the business model. So 
I haven't done the caching thing in a bit :-).
