[erlang-questions] Are you using {packet, http} ?

[Justin Sheehy]

Sverker,

Mochiweb also uses the undocumented http mode for sockets.

I think (offhand, without checking) that it uses it in passive mode and
wouldn't care about the change, but you may want to get one of the mochiweb
developers would need to chime in as an authoritative voice.  But as a heavy
user of mochiweb I wanted to make sure that you were aware of it as another
implementation relying on this.

I'm very glad you're making it official.  It's a great feature.

Thanks!

-Justin
