Vern,
I'll give that a try.
Where do you set the '-vv'?
Here's update from IBM.
"I think I know what the issue is, at 710 when you create a new Apache server it adds the Traceenable Off to the config file, at 610 it does not. So if you have a server at 610 and upgraded to 710 you will still need to add this directive. So it's misleading in the infocenter."
So I need to revisit every instance and add the directive, then

I wonder if you'd get the info you want if you start the Apache instance in verbose mode, make a normal connection in your browser, then shut off the instance - you get a bunch of spooled files with all kinds of info on what was done.
You use '-vv' in the options to get verbose mode.

Did the default change from V6R1 to V7R1, or could there be a typo in the center.
With Windows7 , can't use the recommended TELNET test to confirm the status.
"Normally you will have this enabled by default, but if you want to test if it is really enabled on your server you just have to telnet on the port your web server is running and request for "TRACE / HTTP/1.0" if you get a positive reply it means TRACE is enabled on your system.
Any recommendations on how to confirm.

So even if TraceEnable is not in the httpconf file, by default it is off.

According to the InfoCenter directive reference, if not specified the
default is
TraceEnable off

Security audit is requesting that these vulnerabilities be disabled.
Reviewing the httpd.conf config files, I see no evidence of TRACE and/or TRACK, so I'm assuming these are on by default, and need to be disabled by one of the suggested methods.
All of our HTTP instances are Apache 2.2.11(i5).
Am I correct that I need to re-visit every HTTP instance, adding one of the two recommendations below.
To disable
TraceEnabled Off
OR
...
# disable TRACE in the main scope of httpd.conf RewriteEngine On RewriteCond %{REQUEST_METHOD} ^TRACE RewriteRule .* - [F] ...
<VirtualHost www.example.com>
...
# disable TRACE in the www.example.com virtual host RewriteEngine On
RewriteCond %{REQUEST_METHOD} ^TRACE RewriteRule .* - [F]
</VirtualHost>
mod_rewrite must be active for these directives to be accepted. If mod_rewrite is not already active in your configuration:
Plugin Text: Synopsis: Debugging functions are enabled on the
remote web server.
Description: The remote web server supports the TRACE and/or TRACK
methods. TRACE and TRACK are HTTP methods that are used to debug web
server connections.
Solution: Disable these methods. Refer to the plugin output for more
information.

To disable these methods, add the following lines for each virtual
host in your configuration file :
RewriteEngine on
RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK) RewriteRule .* - [F]
Alternatively, note that Apache versions 1.3.34, 2.0.55, and 2.2
support disabling the TRACE method natively via the 'TraceEnable'
directive.
