Transport
HTTP/0.9 and HTTP/1.0:
- Made the Web popular
- Design flaws and implementation problems caused poor performance
HTTP/1.1:
- Addresses some of these problems
- 60% server support, client & proxy support beginning
- Performance benefits! (optimised implementation reduces packet traffic by 2/3)
- Is acting as fire-fighter
- Poor usage counting
- Not sufficiently flexible or extensible
