HTTP TRACE request method returns HTTP header information, which you can use to debug code. By default, the HTTP TRACE function is disabled on the Mid Tier. To enable the function, add the following line to the config.properties file:
arsystem.enableHttpTrace=true
Warning
The Mid Tierhas no control over the host application server. If the host server is not configured to have HTTP TRACE disabled, then the information that the host discloses still exists.
