How to log raw HTTP messages with OpenEdge Http client

How to log raw HTTP messages with HttpClient?

When using the OpenEdge.Net.pl code, is it possible to capture the request and response as they are sent over the network ?

Enable extended logging for HTTP Client introduced in OpenEdge 11.5

In OpenEdge 11.5.1

• The HTTP request and response information is dumped by adding the following statement at the beginning of the application

• The SESSION:DEBUG-ALERT = TRUE statement writes the following files into the client temporary directory (-T) otherwise current working directory:
  • request-raw.txt
  • response-data-received.txt

In OpenEdge 11.6.x, 11.7.x and 12.x

• The HTTP request and response information is dumped by setting the LOG-MANAGER:LOGGING-LEVEL to 5 at the beginning of the application. 
• This writes the following files into the client temporary directory (-T) otherwise current working directory:
  • request-raw.txt
  • response-data-received.txt 
• In addition, when LOG-MANAGER:LOGFILE-NAME is specified that log will contain additional debugging messages, including for example the time taken and bytes read per request/response, HTTP chunks received.

In OpenEdge 12.5, 12.6 and later

• Tracing functionality was added in HTTPClient. For details, please refer to this link https://docs.progress.com/bundle/openedge-abl-develop-http-clients/page/Debug-problems-using-ABL-HTTP-tracing.htm
