 Savannah handles three types of hosts redirection:
 
-1. shortcut URL to full URL (.e.g `*.sv.gnu.org` => `*.savannah.gnu.org`).

+File redirection
+----------------

+Since July 2020, Savannah serves user-supplied files from a separate
+domain for security reasons.  Old URLs are redirected to that domain,
+non-file requests are redirected to the main domain.
