http://www.w3.org/Bugs/Public/show_bug.cgi?id=14310 --- Comment #3 from Offbeatmammal <offbeatmammal@gmail.com> 2011-10-02 21:05:05 UTC --- some CDNs with multiple PoPs (points of presence, nodes or other similar term) can add additional header information to indicate which pop/nodes was actually used to deliver content to the user for instance... the origin for the video file may be in your data center but you distribute it via a CDN with nodes in San Fran, Columbus ,Atlanta, Denver, NYC, and London... and they logic should determine which pop delivers content to a consumer in LA, Detroit or Bonn. For tracking/debug the CDN injects some additional information (either as a header or a cookie) to indicate which POP it was served from / where the user has affinity for the current session. In some scenarios a POP may be having an issue, it may have bad content (old or corrupt) cached or it may simply be that for network logic reasons it's not the right node to affiliate a particular user to ... by allowing the requesting client to access that information (something we do have in Flash, Silverlight etc) and report it back to a QA system it's possible to carry out the same level of debugging or reporting -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
