On Awstats, one of the sections displays as it follows:
Successful hits on favicon.ico -> 49.9%
Then, under 404s, i have the following:
Document Not Found (hits on favicon excluded)
Therefore, if the 50.1% of errors on favicon are due to 404s, I wouldn't be able to see them.
I'm pretty sure, the errors on favicon are not 404s, as i have extensivly checked (I might be wrong though). If that assumption is correct, how come 50.1% are not successful hits? Is it because some browsers/tablets/phones don't support it?
Additionally, I store the favicon icon in a folder, but a favicon.ico empty file always appears on my root folder if deleted. That file was replaced with mine, so the error should also not be there.
