How to install mod_websocket with Lighttpd? - node.js

Question

I want to make Lighttpd works with websocket (Socket.IO) and it appears the only way to do so is to install an additionnal module: mod_websocket. I followed these steps but I think I don't get the right /path/to/lighttpd_top_srcdir. I used /usr/lib/lighttpd as I saw all the modules in here when I ls-ed it.
Apparently, I need to reinstall Lighttpd, am I right?
So far, I got
copy mod_websocket files into /usr/lib/lighttpd
cp src/mod_websocket*.{h,c} /usr/lib/lighttpd/src
cp: target « /usr/lib/lighttpd/src » is not a directory
I need to do this because the error I get when trying to make websockets work is the following: WebSocket connection to 'ws://<myURL>/socket.io/1/websocket/agXkznae1gmlDTutzJyk' failed: Unrecognized frame opcode: 5 (I use Google Chrome v33.0.1750.154).
Is there another way to make websockets work with Lighttpd or do I need to change webserver?
Many thanks!

I resolved my problem!
I used HAProxy instead of Lighttpd mod_proxy as specified in this question
Here is my conf file (amend <...> per your configuration):
# this config needs haproxy-1.1.28 or haproxy-1.2.1
global
log 127.0.0.1 local0
log 127.0.0.1 local1 notice
maxconn 4096
uid 99
gid 99
daemon
defaults
log global
mode http
option httplog
option dontlognull
retries 3
option http-use-proxy-header
option redispatch
option http-server-close
maxconn 2000
contimeout 5000
clitimeout 50000
srvtimeout 50000
frontend public
bind *:80
acl is_example hdr_end(host) -i <URL.toyourwebsite.com>
acl is_websocket hdr(Upgrade) -i WebSocket
acl is_websocket path_beg -i /websockets
use_backend ws if is_websocket is_example
default_backend www
backend ws
balance roundrobin
option forwardfor # This sets X-Forwarded-For
timeout queue 5000
timeout server 86400000
timeout connect 86400000
server apiserver localhost:<PORT> weight 1 maxconn 1024 check
And I made Lighttpd listened to the 8080 port (otherwise HAProxy wouldn't start).
