I know how to force refresh a favicon on a website.
But I would really like to know the reason why it is common with all browsers to refresh favicons in such huge time intervals. After all, images get refreshed much more often.
I'm not looking for a solution, I would just like to know the why.
Because many servers are configured to tell the browsers to cache (save) files like favicons to reduce the number of requests for files that rarely change.
