Thomas said:Not even that. "SHOULD" specifies a strong recommendation,
not a requirement (that would be "MUST"). See RFC2616, 14.43,
and RFC2119.
But SHOULDs must be implemented in order for a UA to have an
"unconditionally compliant" HTTP 1.1 implementation, and we may as well
assume that that is what they would be aiming at.
