CentOS - Mar 2011 - Can anyone help me understand Apache Errors?

LogWatch reports items like:

 Connection attempts using mod_proxy:
   83.167.123.83 -> 205.188.251.1:443: 1 Time(s)
   83.167.123.83 -> 64.12.202.36:443: 2 Time(s)

 Requests with error response codes
   403 Forbidden
      205.188.251.1:443: 1 Time(s)
      64.12.202.36:443: 2 Time(s)
   404 Not Found
      //jmx-console/HtmlAdaptor: 1 Time(s)
      /VINT_1984_THINK_DIFFERENT: 1 Time(s)
      /mobo.png: 1 Time(s)
      /player.swf: 1 Time(s)
      /robots.txt: 4 Time(s)

Now, I know mod_proxy is turned off by default, but is there a way to "play
games" with those that attempt a proxy connection? Like a ReWrite rule or
some sort?

For the 404's, Obviously these don't exist, but robots.txt so I am not
sure
why that has a 404.

What are 406 errors? Some Googling say they are due to mod_security issues
and that an .htaccess fix can turn it off. But I don't understand the issue
and the solution to be honest.

What am I missing?

HTTP status codes generally:

    http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html


Slightly more user-friendly descriptive guide:

    http://www.addedbytes.com/for-beginners/http-status-codes/


406 indicates an unacceptable request.

Bumping up your apache debug levels and watching the error log may help,
as could snooping the traffic generating the request (packet/GET
request).
