I'm having a problem getting any response from urlfetch.Transport.RoundTrip in GAE Go. When I browse a page that makes the call in a browser, the call is executed as intended. When the same function is called from a POST request made by poclbm Bitcoin miner, I can't get a response.
The call is made by this package I made at line 77.
Is it possible, that in Google App Engine one can request data from other web pages under a HTTP GET, but not POST, or is there something else that can be causing this problem?
