[erlang-questions] erlang http tcp_closed problem

[Przemysław Wycisk]

The reason of that behaviour was option packet_size on socket. Default set
of this option ({packet_size, 0}) should mean no size (line size in http)
limit shouldn't it?, but packets were dropped because of large cookie
header.
I consider it as a bug, and also i think that if line size limit in http
socket occurs i should get http_error instead of tcp_closed, it's quite
confusing.
