Corresponds to the numbers in Figure 15-8.

If JSP compilation is required, the trace is collected after the JSP compilation is executed.
The following figure shows the trace collection points when an in-process HTTP server is used.

Because the request information is received from the client more than once at the points 1 and 2, the trace information is also output more than once.
Because the response information is sent to the client more than once at the points 8 and 9, the trace information is also output more than once.
Even when a request for the request body information, and a response are sent from the filter, the trace for points 2 or 8, and points 8 and 9 is output.
