Click follow TCP stream on Frame 4 in the supplied snoop.

It shows client -> server stream having non HTTP data in it, you will see
client->server traffic with the word "entity" without any other headers.

However, if you go over the actual packets in the stream, there isn't any
packet with the word "entity"
