I'd save function renaming for another CL.

These 2 methods are only used locally, so thought I'd go ahead in this cl.
Please let me know if you have a strong preference otherwise, and I'll revert

     const net::HttpResponseHeaders* headers,
     const std::string& action_prefix,

Done. Moved comment to .cc.
