As far as I know, that is correct: Apache HTTP Server does not implement 
the TRACK method.  I don't know of any reference that explains this, but 
you can check the source code:  see the function 
ap_method_registry_init() in the file modules/http/http_protocol.c   If 
you are looking at the latest (unreleased) source code, then see lines 
439 - 474 at

As you can see, "TRACK" is not in the list of methods registered.

You can double-check this by searching all of the Apache HTTP Server 
source code for the word "TRACK" as well as for any calls to the 
function ap_method_register().  ap_method_register() is how modules such 
as mod_dav add support for new methods to Apache HTTP Server.

I hope this helps.
