Sorry.
What I meant is that, in HTTP 1.1, only headers with values separed by
"," can be splitted on multiple lines:

"""Multiple message-header fields with the same field-name MAY be 
present in a message if and only if the entire field-value for that 
header field is defined as a comma-separated list [i.e., #(values)]"""


However the Cookie header uses ";" as the separator.


P.S.
reading the RFC 2965, I see a:
cookie  =  "Cookie:" cookie-version 1*((";" | ",") cookie-value)

so it seems that both ";" and "," can be used...
