Hmm, that makes it an interesting problem to solve this end -- as this
behaviour is entirely dependent, as far as I can see, on the host web
server.  In my case, Apache 1.3.  The only thing I could think to do
would be to instruct users to ensure they force HTTP 1.0 on their
XML-RPC endpoint (I don't even know if this is possible, I've only ever
seen this enforced in Apache httpd via the BrowserMatch directive).

As obviously there appears to be no guarantee for you that servers using
PHP XML-RPC will do the right thing, and I don't appear to be able to
make a change to enforce it, then I think it's up to you...

All suggestions for workarounds welcome.
