Your description of the problem is not very accurate.

The LWP manpage says :
The library automatically adds a "Host" and a "Content-
Length" header to the HTTP request before it is sent over
the network.
The "Host" header is the host name specified in the requested URL. It is
used by (recent) web servers to determine which virtual domain should be
used when several domains are hosted on the same machine. Thus, the answer
to your question is close to "no".

I don't know. Can you produce a test case?
