I haven't checked the specs but I don't think HTTP supports this at all.

What it does support is the HEAD method: you can ask for just the headers
of a document.  The headers include its content length.  Most servers
support it - but it won't work on many dynamically generated documents
or on POST results.

Yes.

In HTTP 1.0 the connection isn't kept alive anyway.
