From: Tony Finch <fanf@demon.net>

The patch below adds accelerator mode functionality to tcp-banger2. In
this mode it makes requests like
        PURGE /path/to/file HTTP/1.0
        Host: www.example.com
instead of
        PURGE http://www.example.com/path/to/file HTTP/1.0

We use it for keeping our accelerators up-to-date with respect to
customer changes on their sites.
