REST: Correct HTTP Response Code For a POST Which Is Ignored
We have a REST API which clients routinely POST and PUT data to. When they do this, sometimes they POST data which results in no change on our system.

HTTP Caching, Browsers weirdeness and everything else!
Yesterday I've tried to get serious about rightly caching some PHP generated pages (think "Articles with comments"). Big fail. Long story short: I set the ETag header, set the Last-Modified one and check server side every Article browser request with them to see if I can send back a 304.
