Hi,

I'm trying to use lhttpc with OTP HEAD from github and ran in to troubles
when trying to call ssl:setopts(S, [{packet, httph}]). I started poking
around and found this in the inet manual:
"Note that the packet type httph is not needed when reading from a socket."
Apart from that I can't find any reference to httph any more. I'm not sure
what's meant by that but I guess I'm missing something here. I'm using
packet type httph to read trailers after chunked transfer coding.

Is packet type httph intentionally removed, and will it be so from pure tcp
sockets also?

Thanks
/Oscar

Hi!

This was discussed a bit of list as I happend to reply from the wrong
email address (sorry about that).
Anyway here is the conclution.

Packet httph was invented for the statless erlang:decode_packet/3
function (used for example by the ssl application), howerver gen_tcp
and ssl sockets will
switch atomatically from http to httph after receiving the
request/status line, hence we did not see the need to be able to set
httph an ssl option.

When using gen_tcp you happen to be able to use packet httph in an
other context e.i. parsing trailers from chunked encoding, which is
quite logical as
they are defined to be entity-headers in the HTTP RFC. So what happens
to work for gen_tcp we think is the desired behaviour and we will
update
ssl to handle it too. We wil also update the inet documentation.
