A logical conjunction (' && ') request condition that matches a request against
a set of header expressions with syntax defined in RequestMapping.headers()
.
Expressions passed to the constructor with header names 'Accept' or
'Content-Type' are ignored. See ConsumesRequestCondition
and
ProducesRequestCondition
for those.
