Favicons. I know that they were groundbreaking when they first sprang
into existence and use, but I barely remember those days anymore (that
was 20 years ago!). But now my server logs are filling up with HTTP 404
errors because I haven't created and placed a
favicon.ico file at
the root of the site.
To resolve this problem, I created an additional directive in my
server configuration. Now, all requests for
return HTTP 204 No Content. "Yes, I got your request. No, I have no
content for you to display."
I'll eventually add a favicon, but for now I've resolved the 404 errors that are caused by these automatic requests.
