3.9   What is HTTP/1.1?

   HTTP/1.1 is a new standard transmission protocol for the world wide web.
The  HTTP/1.1 standard allows the browser to negotiate "chunked" transfers,
resume  aborted  downloads,  and  many  other  low-level  but highly useful
things.

   The  major  benefit  of  HTTP/1.1  is  this:   under a "normal" HTTP/1.0
transmission,  your  browser  must  open  a new connection for every image,
animation,  or  text  document  on  a  page.  Each of these transfers has a
normal  "speed  curve"  -- they start out slow and get gradually faster the
longer  they  last.  On a page with many small pictures, this leads to long
load times because each graphic is going through its own "speed curve".  On
an  HTTP/1.1  server,  a  single transfer can contain many of the graphics,
thus sharing the "speed curve", and allowing the page to load faster.

   HTTP/1.1  must  be  supported  both  at the browser level and the server
level.  Many sites are switching to HTTP/1.1 servers.
