One of the changes in Apple’s release of iOS6 last week was a surprising new ability to cache POST responses.
One of the concerns that often comes up when someone creates a new HTTP header is how much “bloat” it will add on the network. This is especially relevant in requests, when a little bit of extra data can introduce a lot of latency when repeated on every request.
A lot of people seem to be talking about and performing load tests on HTTP servers, perhaps because there’s a lot more choice of servers these days.
