guys i need any forward proxy software which supports http/1.1 so as to use the Host feature of the http 1.1

i tried squid,ziproxy
but the problem is i get the response like this : -

Send to HTTP proxy: 'CONNECT 204.xxx.xxx.xxx:443 HTTP/1.1'
Thu Nov 01 21:15:12 2012 HTTP proxy returned: 'HTTP/1.0 200 Connection established
it turns my http/1.1 request to http 1.0 (btw the above lines is from openvpn trying to connect via a proxy)

one lan proxy i tried which was giving the things correct
Send to HTTP proxy: 'CONNECT 204.xx.xx.xx:443 HTTP/1.1'
Thu Nov 01 21:15:12 2012 HTTP proxy returned: 'HTTP/1.1 200 Connection established
it gives http/1.1 connection established , i cant know what software the server is using coz its not under my reach ..

so guys please tell me which forward proxy will serve and give me http/1.1 connection establish replies .....
Thanks !!
