+ *    - Repeat the request URL before logging any headers.
+ *      Makes reading the log easier in case of simultaneous requests.
+ *    - If there are more than one Content-Type headers in one request,
+ *      use the first one and remove the others.
+ *    - Remove "newval" variable in server_content_type().
+ *      It's only used once.
