also, in a lot of cases TCP connection splitting is implemented exactly 
in the form of a proxy(i.e at the application layer with sockets etc...)
so TCP connection splitting maintains just about as much state as 
any other caching proxy...

just as incorrect operation of TCP connection splitting can cause 
consistency problems..so can incorrect operation of caches...
e.g. the cache can serve up stale pages..(if its not working correctly..)
just the TCP connection splitting can cause loss of data if its not 
working correctly...
