This code produced the following header:

Could someone help me how exactly generate the header I need?

What do you mean by "asynchronous logging"?

7. Asynchronous Logging
Tomcat 7 now includes an asynchronous file logger (AsyncFileHandler). AsyncFileHandler extends FileHandler and can be used in place of FileHandler. To use AsyncFileHandler, simply replace all occurrences of FileHandler with AsyncFileHandler in the CATALINA_HOME/conf/logging.properties file. The application must use java.util.Logging; asynchronous logging does not work with Log4j.

When a log message is sent to the AsyncFileHandler, the log message is added to a queue(java.util.concurrent.LinkedBlockingDeque) and the method invocation to log a message returns immediately without waiting for the I/O to disc. A separate thread is started when the AsyncFileHandler is loaded by the class loader. This thread reads log messages from the queue and writes them to the disc.

The advantage of this approach is that if the I/O to disc is slow (e.g. log files on a remote drive), logging will not slow request processing.

AsyncFileHandler employs a producer/consumer relationship with the queue to store log messages. The default queue size is 10000. In case of overflow, the default behavior is to drop the last message. Both the default size and overflow behavior can be configured using startup system properties.

Hi Folks
I have found many tutorials to use asynchronous logging in tomcat7 but I'm not finding to tomcat8.
How do I use asynchronous logging in tomcat8? It seems to me that is setting by default?
Best Regards.

I also had these problems, but I decided to make simulator before the oficial certification and that's what got me through.

Yeap! You are compulsory to attend at least 1 course of oracle that can be done before, during or after being approved in the other phases...
Congrats and welcome to the team!
In my opinion is a bad option ... REST has no failure and recovery mechanism. In this case the best would be JMS. Think about it ....
It is only you put in SSL connections on the deployment diagram ... no needs explanation.
