The syntax for the Set-Cookie response header is:

 set-cookie      =    "Set-Cookie:" cookies
 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:

parse in interface CookieSpec

Parameters:

host - the host from which the Set-Cookie value was received

port - the port from which the Set-Cookie value was received

path - the path from which the Set-Cookie value was received

header - the Set-Cookie received from the server

Returns:

an array of Cookies parsed from the Set-Cookie value

Throws:

MalformedCookieException - if an exception occurs during parsing
