Http connect to proxy to websockets

I am having a hard time with this one. We have a websocket server listening on port 80 at myserver.com/wsDemo?ID=12. We need to test a client program by connecting it to this server through a proxy. I am trying nginx 1.2.7 as the proxy on port 8080, running on proxy-server. We want the client to connect to the proxy using http connect method, and then have the proxy create a tunnel to the myserver.com/wsDemo?ID=12 websocket app server. Here is my nginx config:
Code:
http { include /etc/nginx/mime.types; default_type application/octet-stream;

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

access_log  /var/log/nginx/access.log  main;

sendfile        on;
#tcp_nopush     on;

#keepalive_timeout  0;
keepalive_timeout  65;

gzip  on;
server{
    listen  8080;
    listen  80;

    location /wsDemo?ID=12 {
            proxy_pass http://myserver.com:80/wsDemo?ID=12;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
    }
}

# Load config files from the /etc/nginx/conf.d directory
# The default server is in conf.d/default.conf
include /etc/nginx/conf.d/*.conf;
}

ssh-http-proxy-connect(1)					   User Commands					 ssh-http-proxy-connect(1)

NAME
ssh-http-proxy-connect - Secure Shell proxy for HTTP SYNOPSIS
/usr/lib/ssh/ssh-http-proxy-connect [-h http_proxy_host] [-p http_proxy_port] connect_host connect_port DESCRIPTION
A proxy command for ssh(1) that uses HTTP CONNECT. Typical use is where connections external to a network are only allowed via a proxy web server. OPTIONS
The following options are supported: -h http_proxy_host Specifies the proxy web server through which to connect. Overrides the HTTPPROXY and http_proxy environment vari- ables if they are set. -p http_proxy_port Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the HTTP- PROXYPORT and http_proxy environment variables if they are set. OPERANDS
The following operands are supported: http_proxy_host The host name or IP address (IPv4 or IPv6) of the proxy. http_proxy_port The numeric port number to connect to on http_proxy_host. connect_host The name of the remote host to which the proxy web server is to connect you. connect_port The numeric port number of the proxy web server to connect you to on http_proxy_host. EXAMPLES
The recommended way to use a proxy connection command is to configure the ProxyCommand in ssh_config(4) (see Example 1 and Example 2). Example 3 shows how the proxy command can be specified on the command line when running ssh(1). Example 1: Setting the proxy from the environment The following example uses ssh-http-proxy-connect in ssh_config(4) when the proxy is set from the environment: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect playtime.foo.com 22 Example 2: Overriding proxy environment variables The following example uses ssh-http-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect -h webcache -p 8080 playtime.foo.com 22 Example 3: Using the command line The following example uses ssh-http-proxy-connect from the ssh(1) command line: example$ ssh -o'ProxyCommand="/usr/lib/ssh/ssh-http-proxy-connect -h webcache -p 8080 playtime.foo.com 22"' playtime.foo.com ENVIRONMENT VARIABLES
HTTPPROXY Takes the http_proxy_host operand to specify the default proxy host. Overrides http_proxy if both are set. HTTPPROXYPORT Takes the http_proxy_port operand to specify the default proxy port. Ignored if HTTPPROXY is not set. http_proxy URL format for specifying proxy host and port. EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 An error occurred. ATTRIBUTES
