Correct. Or simply configure your useragent not to use keep-alive (if it
does support it at all).

But why do you want to know this at all?
If you are interested in the technical details, read the RFC2616
<http://www.faqs.org/rfcs/rfc2616.html>. Some basics about TCP/IP might
also help.
If you are concerned about your privacy: I never heard of someone using
keep-alive as a way to track users (which does not imply anything ;) - at
least someone has spent some (not really much) thoughts on this:
