Local Favicon Cache
By Timo van Neerden
This script uses a Google Service to constitute a local favicon cache.
The first time a favicon for any given domain-name or URL is requested, the script asks the google-service for the favicon and stores it locally. The next time a favicon for the same domain is requested, the locally stored icon is served.
This avoids network cross-sites requests and therefore enhances user-privacy (no google-requests).

This script is based upon Mitsu's gravatar-cache script, which is basically the same script but for Gravatar icons.
