Hello all,

In the documentation of the t_relay_cancel() (TM module) there is an example that reads:

if (method == CANCEL) {
if (!t_relay_cancel()) {  # implicit drop if relaying was successful,
                                  # nothing to do

# corresponding INVITE transaction found but error occurred
sl_reply("500", "Internal Server Error");
drop;
}
# bad luck, corresponding INVITE transaction is missing,
# do the same as for INVITEs
}

What bothers me is the phrase #do the same as or INVITEs, because in RFC(http://tools.ietf.org/html/rfc3261#section-16.10 )  it says:

If a response context is not found, the element does not have any
knowledge of the request to apply the CANCEL to.  It MUST statelessly
forward the CANCEL request (it may have statelessly forwarded the
associated request previously).

So aren't we supposed to immediately statelessly forward the CANCEL if t_relay_cancel() did not find the INVITE transaction, instead of doing the same as INVITEs, which could be t_relay() (not stateless)?. Like below:


if (method == CANCEL) {
	if (!t_relay_cancel()) {  # implicit drop if relaying was successful,


                                  # nothing to do



		# corresponding INVITE transaction found but error occurred

		sl_reply("500", "Internal Server Error");
		drop;


	}
        # bad luck, corresponding INVITE transaction is missing,


	forward();
}



Am I correct or am i missing something?


Thank you in advance,
Bill
