+ * Formats log messages using variable substitutions for requests, responses,
+ * and other transactional data.
+ *
+ * The following variable substitutions are supported:
+ *
+ * - {request}:      Full HTTP request message
+ * - {response}:     Full HTTP response message
+ * - {ts}:           Timestamp
+ * - {host}:         Host of the request
+ * - {method}:       Method of the request
+ * - {url}:          URL of the request
+ * - {host}:         Host of the request
+ * - {protocol}:     Request protocol
+ * - {version}:      Protocol version
+ * - {resource}:     Resource of the request (path + query + fragment)
+ * - {hostname}:     Hostname of the machine that sent the request
+ * - {code}:         Status code of the response (if available)
+ * - {phrase}:       Reason phrase of the response  (if available)
+ * - {error}:        Any error messages (if available)
+ * - {req_header_*}: Replace `*` with the lowercased name of a request header to add to the message
+ * - {res_header_*}: Replace `*` with the lowercased name of a response header to add to the message
+ * - {req_headers}:  Request headers
+ * - {res_headers}:  Response headers
