Requests that span more than one TCP packet are misinterpreted.

[bensherman]

If one makes a request to a server that is large (say, larger than the current MTU), and it is broken up in the network, the second packet will get misinterpreted as a new request and does all sorts of nutty things, depending on what data overflows into the subsequent packets.

I suspect that multiple requests in the same packet may be ignored.
