Re: [reSIProcate] missing Max-Forwards in CANCEL

CANCEL is a single-hop request, and therefore doesn't really need a Max-Forwards header. However, RFC 3261 mandates it, so I am leaning in the direction of just adding it. Any objections? 

Best regards,
Byron Campen


Mandatory header Max-Forwards missing in CANCEL.
