# NOTE:
# Some of the below redirects are 302s, and some are 301s. 302s are used
# for redirects whose targets change sometimes. For example:
# - /docs/ -> /docs/fr/, /docs/en/, etc.
# - /docs/en/ -> /docs/en/edge/, /docs/en/latest/, etc.
# - /docs/en/latest -> /docs/en/4.0.0/, /docs/en/5.0.0/, etc.
#
# 301s are for PERMANENT redirects. These are used only for mapping old
# docs pages to new docs pages.
# 302:
# docs -> docs/en/latest/
# docs/ -> docs/en/latest/
# docs/XX -> docs/XX/latest/
# docs/XX/ -> docs/XX/latest/
#
# NOTE:
# these can both apply, turning "/docs" into "/docs/en/latest/"

# NOTE:
# This does NOT return a redirect. It returns the resource *as if* the
# redirected URI was requested. That is, both URIs return the same
# resource, but the browser won't change the URI (no redirects followed).
