I'm not terribly familiar with the Apache log format. Are you sure that
the log records the protocol level in the request, or the protocol level
of the response? The standard Apache config files include a rule to
downgrade certain user agents to HTTP 1.0. Is this rule in your config
file?
Might an intervening proxy downgrade the request to 1.0?
