Supressing the last modified header is just an add_header Last-Modified ""; away.
You'll also need: # Don't honour client If-Modified-Since constraints. if_modified_since off; # Nginx's etags are hashes of file timestamp & file length. etag off;Turning these off will of course prevent all caching. I don't know if that would add measurable load to guix.gnu.org (it would be more problematic if we used a CDN, but it might still make a difference).
Nix does something both interesting and icky — as always: patch[0] nginx to look up the realpath() instead, so clients can still cache using If-None-Match.
