+# GoogleICS
+
+Allows for a proxy from CloudFlare to public calendars on google in iCS format.
+
+This will allow for requests to Google from a mobile device to not come from
+a geolocatable IP address. Using CloudFlare workers for this also gets you to
+use a cached edge location. Technically Google tracking would still be
+available at a regional level (constrained to CloudFlare's edge locations).
+However, Google would lose the ability to track to a single user.
+
+Specifically, they will get:
+
+* Time and IP address of CloudFlare edge location
+* The following custom header: `CDN-Loop: cloudflare`
+
+Note that CloudFlare has full knowledge of requests, etc, so this is somewhat
+trading of trust from Google (AdTech company) for CloudFlare (makes money from
+CDN and DDOS mitigation).
