Regression fix for exporting access logging functions
Review Request #6973 — Created Feb. 23, 2015 and submitted
I ran into a bug I introduced when testing rb-gateway. The access logging won't work unless the WriteHeader and Write functions are exported. Otherwise, the default 200 OK response will always be returned with a content length of 0.
Ran any invalid API request and verified that the response was not 200 OK.
