bastodon/config/initializers/preload_link_headers.rb

# Since Rails 6.1, ActionView adds preload links for javascript files
# in the Links header per default.

# In our case, that will bloat headers too much and potentially cause
# issues with reverse proxies. Furthermore, we don't need those links,
# as we already output them as HTML link tags.
