HTTPAPI supports via the http_setproxy() API

If authentication is required for the proxy ("web applications 
firewall") then HTTPAPI supports BASIC authentication.  (But not NTLM or 
NTLMv2 at this time.)

If you use a proxy, HTTPAPI always connects to the proxy, nowhere else, 
and therefore the proxy is the only hostname HTTPAPI needs to resolve. 
Any other hostname is resolved by the proxy itself (not by HTTPAPI) so 
there'd be no need for local DNS resolution.  (at least, as far as 
HTTPAPI is concerned... )

I don't agree...   but then, I don't know much about Google Calendar 
services.

Anyway, if you want to try it, you'll want to put code like this into 
your application, prior to doing any GET/POST with HTTPAPI:

      http_setProxy( 'proxy.whatever.com': 8080 );

Where proxy.whatever.com is the name of the proxy server ("web 
application firewall") and 8080 is the port number.

Or, with authentication:

      http_setProxy( 'proxy.whatever.com': 8080 );

      http_proxy_setAuth( HTTP_AUTH_BASIC
                        : 'the username'
                        : 'the password' );

Once that has been done, HTTPAPI will let the proxy handle the rest.
