* 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}: ISO 8601 date in GMT
* - {date_iso_8601} ISO 8601 date in GMT
* - {date_common_log} Apache common log date using the configured timezone.
* - {host}: Host of the request
* - {method}: Method of the request
* - {uri}: URI of the request
* - {version}: Protocol version
* - {target}: Request target 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
* - {req_body}: Request body
* - {res_body}: Response body
* Apache Common Log Format.

It is recommended that you Edit text format, this type of Fix handles quite a lot in one request
