This is for short URLs and no cookies (except those injected by operators) are included. 0 : 18.9% 100 : 1.6% 200 : 7.7% 300 : 9.8% 400 : 8.4% 500 : 11.1% 600 : 11.4% 700 : 9.5% 800 : 7.7% 900 : 4.7% 1000 : 2.4% Almost all of these are however request invariant, so just setting these on a connection level solves most of the problem without compression or compact encoding. /Martin Nilsson
