Calling Web Service from a BSP

Has anyone successfully called one of the Google search engine web services from 6.20? Or any external, non-R/3 web service for that matter? When I run test connection on a RFC destination type G (HTTP connection to External Server), it returns ICM_HTTP_CONNECTION_FAILED message. I am using api.google.com for Target Host and /search/beta2/ for Path Prefix; all other fields are blank/default. I was able to setup the RFC destination for type H (HTTP connection to R/3 system) correctly and run the sample ABAP web service client program (from SAP Help which calls STFC_CONNECTION).

Any help will be appreciated.

Thanks, Pradeep
