Document Summary
Content delivery networks - put your data on an origin server, and then replicate on many other servers. Determines the closest server to reach to get your data. Expires: don"t fetch the data until after this date! X-cache: determines whether or not the data could be grabbed from the local cache. No, unless you"re okay with caching it for the period. There are a lot of dependencies underneath with which you cannot change if you cache. Well images are usually static , so sure let"s cache them! Linking to other parties for their data is dangerous (and you should need headers to negotiate the safety of the data!) Captchas: a perfect example of punishing the many for the existence of the few . Who is allowed to talk to me? . Intentionally using bad requests to sniff out information and see how you react.
