This trivial App Engine app serves the small meta+redirector HTML pages for https://google.golang.org/. For example:
The page includes a meta tag to instruct the go tool to translate e.g. the import path “google.golang.org/appengine” to “github.com/golang/appengine”. See go help importpath
for the mechanics.
To update the public site, run:
