 * @param request

 *     content may have been released already, so you cannot rely on any of the methods that return the payload
 *     content in any form.
 * @param finalResponseObject
 *     The {@link HttpResponse} that was the actual final response object sent to the client; may be null. NOTE:
 *     This should be preferred over {@code responseInfo} whenever both have overlapping data since this argument
 *     may have been modified by outbound handlers after being initially populated by {@code responseInfo}.
 * @param responseInfo
 *     {@link com.nike.riposte.server.http.ResponseInfo} object that was initially used to build {@code
 *     finalResponseObject}; may be null. NOTE: {@code finalResponseObject} may have been modified by other outbound
 *     handlers (e.g. compression/gzip), so if it is non-null it should be preferred over this where possible.
