Serve rails assets with etags from nginx

nginx.conf

location / {
  if ($uri ~* "/assets/.*-(.*)\..*") {
    expires max;
    add_header Cache-Control public
    add_header Etag $1;
  }
}

You'll probably also want to add the following to serve the already compressed assets

gzip_static on;

Oh definitely. You can't put that in the if statement though, so you should define it globally at the top of nginx.conf.

Ah I don't user an if statement. I have the following:

location ~ ^/assets/.*-(.*)\..* {
    gzip_static on; # to serve pre-gzipped version
    expires max;
    add_header ETag $1;
    add_header Cache-Control public;
    break;
}

but looking at that doesn't make since. I don't know that that just applies to just that location

Pretty sure the gzip stuff can be applied per location, but I just have it defined globally. Doesn't seem to cause any problems to do that.
