Proxying doesn't seem to work

I've Squid (v 2.7) proxying server with some access credentials for development 
purposes, also I've external proxy server Squid (v 2.6).
Testing Squid using pycurl shows that request go via my proxy server 
"DESKTOP:3128" and external Proxy server whether httplib2 doesn't make sense 
proxy or not.

PYCURL CODE:
{{{
import pycurl 

c1 = pycurl.Curl()
c1.setopt(pycurl.URL, 'http://google.com')
c1.setopt(pycurl.PROXY, 'localhost')
c1.setopt(pycurl.PROXYPORT, 3128)
c1.setopt(pycurl.PROXYTYPE, pycurl.PROXYTYPE_HTTP)
c1.setopt(pycurl.PROXYAUTH, pycurl.HTTPAUTH_BASIC)
c1.setopt(pycurl.PROXYUSERPWD, 'user:user')
c1.setopt(pycurl.VERBOSE, 1)

c1.perform()
}}}

PYCURL RESULT:
{{{

}}}

But httplib2 doesn't make sense it gives me back the results of a direct 
request even if I provide wrong parameters.

HTTPLIB2 CODE:

{{{
import httplib2

httplib2.debuglevel = 4

h1 = httplib2.Http(proxy_info = httplib2.ProxyInfo(4, 'localhost', 3128, 
proxy_user = 'user', proxy_pass = 'user'))

h1.request('http://google.com')
}}}

HTTPLIB2 Result:
