Hi guys, We are planning to add a Last-resort routing feature to Traffic Control. It will make TR redirect a request to an alternate domain, an error domain, or an origin server when there is not suitable cache available (e.g. all caches are busy). It is similar with current “Bypass FQDN” in TC, but it adds more parameters like redirecting to error domains or origin servers.
All the new parameters will be configured through “DS Profile” (to avoid GUI and DB schema changes), which is different with the current GUI configuration of “Bypass FQDN”. So the design will not change the current “Bypass FQDN” feature, and just add Last-resort as another extra feature. If Last-resort feature is not enabled (by default), the current behavior of Traffic Router will not change. Please refer to following doc for more details: https://docs.google.com/document/d/1ttrZUGoGZTdCT6g78v62xBVoDCC_cWesPzxfLaHBcp0/edit Any comments are welcome. Thanks, John
