Most HTTP requests will *not* include an absolute URI. Instead, the
request line contains only the path. This is not a bug.
There is a header, host, that can be used to fill in the blank /if it
is present/. Doing this automatically in the web module is too
prescriptive; instead, each server should do this for itself as it
deems appropriate. Also, I would just inspect the host header
directly and *never* manipulate the Request-URI.
<http://tools.ietf.org/html/rfc2616#section-5.1.2>
The host header is typically used by a reverse proxy or virtual host
provider to dispatch to the appropriate site handler/module, which
(usually) should not care what its hostname is.
