From reference:
"    Usage: fossil http REPOSITORY
    Handle a single HTTP request appearing on stdin.  The resulting webpage
    is delivered on stdout.  This method is used to launch an HTTP request
    handler from inetd, for example.  The argument is the name of the    repository.

Test with current Fossil under Windows Vista:<verbatim>
================================================================
http myclone.fossil
GET / HTTP/1.0
Host: localhost

HTTP/1.0 302 Moved Temporarily

So it seems behave right, like declared.
