 cookies         =    1#cookie
 cookie          =    NAME "=" VALUE * (";" cookie-av)
 NAME            =    attr
 VALUE           =    value
 cookie-av       =    "Comment" "=" value
                 |    "Domain" "=" value
                 |    "Max-Age" "=" value
                 |    "Path" "=" value
                 |    "Secure"
                 |    "Version" "=" 1*DIGIT
 

Specified by:
