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...)

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
