uWSGI is currently not compliant with RFC 2616 section 14.10. This will work around the problem by blindly applying the correct header to responses, when using the default uWSGI vassal configuration files. This does break persistent connections in that case, so these configs should probably be changed for production use (or uWSGI should not be used). Change-Id: I56036768c46f1f727b10c7d231c3470dfa8213ea
