Version of google-http-java-client (e.g. 1.15.0-rc)? 1.16.0-rc Java environment (e.g. Java 6, Android 2.3, App Engine)? JSDK 1.6 Describe the problem. There's no "Referer" header - I'm pretty sure. How would you expect it to be fixed? add the following - req.getHeaders().setReferer(String)
Also, I'm not sure that all the headers are passed to the low-level request. Something added to the listener to be allow inspection of the full and final payload (for POST at least) would be handy.
Lastly is it Referer or Referrer in the HTTP spec???
