SSH Proxying Through SSL CONNECT

[Max Hawkins]

I'm attempting to proxy an SSH connection through port 443 so that I  
can break a restrictive firewall while nginx is serving documents via  
SSL at the same time.

I found a python script called http-proxy-tunnel (http://www.stuart.id.au/russell/files/http-proxy-tunnel 
) that will tunnel the SSH using the SSL CONNECT method. The script's  
documentation lists an example server configuration for Apache, but  
I'm not sure how to achieve the same thing in nginx:

AllowCONNECT	22
ProxyRequests	on
<ProxyMatch ^(?!localhost:22$)>
Deny from		all
</ProxyMatch>

Is there an nginx equivalent to this configuration?

Thanks,
