    3. Mixing beresp.ttl and Expires header

    Wow, that's great idea substracting age from my ttl. I assume I'd need std.atoi for that, but it seems easy. Also I'd need to do this math again on edge's vcl_deliver in order to set right cache co...

    Mixing beresp.ttl and Expires header

    2. VCL

    3. Fastly and S3 - dealing with 'read after update' eventual consistency

    Why not do delayed flush. I.e. purge immediatey, then, using resque or any other scheduler, purge after a second and again after minute. Is there any guarantee on s3 update?

    3. Caching strategies for authenticated data

    You can leverage Fatly's cryptographic functions, like digest.hmac_sha256(key, message), have shared secret key between your servers and VCL and use any user's info as message - id, email, id+passw...

    3. Why isn't serve stale working as expected?

    Do you plan on changing this functionality in future? For example, write object to disk if it's need to be thrown out of memory but it still has grace period. It seems to me, that the case that I ...
