"The PING method is used to report a page navigation. The Request-URI 
represents a link auditing listener (terminology?). Source and target of 
the page navigation are reported as (... - insert what's used, headers, 
or request body)."

...statement about general transmission requirements -- both request and 
response can have a message body, to be delimited as per RFC2616. If 
PING doesn't use them it should state that they are currently unused and 
either should be ignore (must ignore) or nor (must understand)...

...statement about cacheability -- state that for tracking to be 
accurate, the server must not indicate that the response is cacheable; 
no caching headers at all should be sufficient...

...state that the method is safe in the sense of RCF2616 (from the 
user's point of view).

Finally, I'd probably choose a less generic term, such as "AUDITNAV" or 
something like that; must people understand "ping" as something different.

BR, Julian
