How can I return a 204 rather than 404 for a missing favicon.ico file in Nginx?
I think this is what you're looking for:
location = /favicon.ico { try_files $uri = 204;}It will try to find the file at the URI or 204 as fallback. Here's the relevant documentation.
A simple
location /favicon.ico { return 204; }would be the easiest.
The important bit is that the = and the HTTP status Code need to be one word and there must not be any space between. If you leave a space between, your error.log will fill quickly as 95% of all requests have a favicon.ico of some sort.
The following should be saved for reusability and just included where necessary.
# (i) No need to log presence or absence.location = /favicon.ico { access_log off; log_not_found off; try_files $uri =204;}
