7. Graph API ETag Support
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 conditionalsrequests with If-None-Match
