After much headache with Ejabberd and some internal discussions, we
talked about Nginx supporting the BOSH protocol. This would allow simple
creation of scalable instant message systems and anything else that
requires stateless connections to act statefully.
Nginx would hold 2 client connections and create a persistent connection
to upstream servers. To even begin to make this possible, Nginx would
need to support persistent connections to upstreams. What is the status
of that feature? Its been listed on the feature request page in the wiki
for a while.
Anyone interested in seeing this?

i don’t think i’d be using it for quite some time but it does sound
cool and yet another thing nginx can excel in.

Can you give more detail?
Thanks.

I can obviously see how clever a lot of it is, but am I the only
person who finds all this Comet/Bayeux/BOSH/Javascript “TCP sockets”/
etc stuff slightly unsettling? If you push and bend (e.g.) HTTP to do
all this stuff it was never intended to do, won’t it, and all the
infrastructure supporting it, eventually just break? OK, so there’s
Jetty and nginx can handle loads of keepalives and so on and so forth,
but …
If people want bidirectional comms with browsers, if they want publish/
subscribe mechanisms, wouldn’t all this work by very clever people be
better directed towards getting a sensible security infrastructure in
place to allow listening sockets in client sandboxes, rather than
building ever bigger wrappers with sticky tape and bits of string?
</devil’s advocate>
A listening socket on the client isn’t going to really work because of
firewalls and other network nastiness. And HTTP is the preferred
method for this kind of thing because it works on browsers without
modifying them. Assuming a new standard were made, it would be a good
number of years before the browsers that most people use would support
them, so the standard would be useless anyway, whereas http works now.

I would be very interested to see support for persistent connections to
upstreams, and the company I’m working for would be willing to
(co)sponsor such a feature. I already contacted Evan M. about this,
but he doesn’t have enough time to pick this up currently. Anyone else
capable of and willing to pick this up?

My company is also willing to add to the bounty for persistent
connection support to upstreams, notably memcached. I simply do not
have the time.

I’ve recently posted here a patch that will allow nginx to know
when request is completed even if backend server wasn’t closed
connection. The patch is currently waiting for Igor’s review.
There are two things left for http persistent connections support:
chunked encoding (should be relatively easy with the mentioned
patch) and saving connections for later use instead of closing
them (relatively easy as is).

AFAIK someone still has to pickup the persistent connection thing.
Several companies are willing to pay bounties for this, and I asked Evan
Miller to do this, but he is currently out of OSS time. I still have
this on my radar though and am still actively seeking for a developer
willing to pick this up. No luck yet though.
Anyone else made any progress?
