So nginx is not interpreting folded headers correctly? - http-headers

Question

HTTP/1.1 header field values can be
folded onto multiple lines if the
continuation line begins with a space
or horizontal tab. All linear white
space, including folding, has the same
semantics as SP. A recipient MAY
replace any linear white space with a
single SP before interpreting the
field value or forwarding the message
downstream.(quoted from here)
Here's my server side script,which just dumps the cookie content:
var_dump($_COOKIE);exit;
Here comes my test,please pay attention to the cookie part:
