Graph API now uses ETags

• A part of standard RFC 2616 HTTP

1. Extract ETag from API Response

2. Use ETag in If-None-Match header

3. If ETag matches, server returns a 304 response

More responsive applications?

• Send less data across the wire in the best cases.

• Recommended usage is for data that won’t change that frequently• Friend lists, albums, etc

• But note: All requests count towards throttling limit• Including conditionals requests with If-None-Match
