Jonathan Sick added a comment - 03/May/16 9:34 AM Implemented in Fastly config version #14! (previous stable was Version #11). Solution was to follow the Fastly docs at https://docs.fastly.com/guides/performance-tuning/generating-http-redirects-at-the-edge Steps are Make a new response called “Redirect from RTD” with Status “301.” Give it a request condition called “URL is /en/latest/“ that applies if req.url ~ "^/en/latest” . Give this condition a priority of 10 so that it applies before all other request conditions (i.e., we want to deal with this specific URL and redirect it first) Create a response Header called “Location for RTD redirect”. This header sets the Location HTTP header to "https://" req.http.Fastly-Orig-Host regsub(req.url, " /en/latest(.+)$", "\1”) . That is, it makes an absolute URL with /en/latest/ stripped out. The response condition is called “Set Location for RTD redirect” and applies if req.url ~ " /en/latest" && resp.status == 301
