Sometimes strange URLs pop up in Google Webmaster Tools. URLs that I know no one link to, like:

	http://example.com/apple-app-site-association

My site is not about apple, apps or site association. I don't know why Google list it as a 404 in Google Webmaster Tools.

Anyway. Should I keep adding these kind of URLs as redirects to the *.htaccess* file when they pop up or should I just let it be?

From a SEO (Search Engine Optimization) perspective.
