There is a difference between errors which happen to a socket - like
receiving EPIPE - an exceptional situation but ultimately okay and the
situation where code throws in a callback - which is not okay.
Fixes test/simple/test-http-exceptions.js
TODO: explain this in docs.
This allows for web servers to be "hijacked" and used as Web Socket servers
(or other). You simply listen for requests as normal, but check if
req.upgrade === true
If so, this will be the last request of the connection. It's your job now to
hijack req.connection and start reading from it. req.upgradeHead is a buffer
containing the first part of the new protocol communication (in the case it
arrived on the same packet).
This needs tests and documentation. API subject to change.
However it's not working very well: Hitting a 'hello world' server with many
requests (ab -t 60 -c 10) will cause it to crash with the following error.
