## Interface CookieStore

-     public interface CookieStore

  A CookieStore object represents a storage for cookie. Can store and retrieve cookies.

  `CookieManager` will call `CookieStore.add` to save cookies for every incoming HTTP response, and call `CookieStore.get` to retrieve cookie for every outgoing HTTP request. A CookieStore is responsible for removing HttpCookie instances which have expired.

  Since:
    1.6

    - #### add

          void add(URI uri,
                 HttpCookie cookie)

      Adds one HTTP cookie to the store. This is called for every incoming HTTP response.

      A cookie to store may or may not be associated with an URI. If it is not associated with an URI, the cookie's domain and path attribute will indicate where it comes from. If it is associated with an URI and its domain and path attribute are not speicifed, given URI will indicate where this cookie comes from.

      If a cookie corresponding to the given URI already exists, then it is replaced with the new one.

      Parameters:
        `uri` - the uri this cookie associated with. if `null`, this cookie will not be associated with an URI
        `cookie` - the cookie to store
      Throws:
        `NullPointerException` - if `cookie` is `null`
      See Also:
        `get(java.net.URI)`

    - #### get

          List<HttpCookie> get(URI uri)

      Retrieve cookies associated with given URI, or whose domain matches the given URI. Only cookies that have not expired are returned. This is called for every outgoing HTTP request.
      Returns:
        an immutable list of HttpCookie, return empty list if no cookies match the given URI
      Throws:
        `NullPointerException` - if `uri` is `null`
      See Also:
        `add(java.net.URI, java.net.HttpCookie)`

    - #### getCookies

          List<HttpCookie> getCookies()

      Get all not-expired cookies in cookie store.
      Returns:
        an immutable list of http cookies; return empty list if there's no http cookie in store

    - #### getURIs

          List<URI> getURIs()

      Get all URIs which identify the cookies in this cookie store.
      Returns:
        an immutable list of URIs; return empty list if no cookie in this cookie store is associated with an URI

    - #### remove

          boolean remove(URI uri,
