• get

  public abstract Map<String,List<String>> get(URI uri,
                                               Map<String,List<String>> requestHeaders)
                                        throws IOException

  Gets all the applicable cookies from a cookie cache for the specified uri in the request header.

  The URI passed as an argument specifies the intended use for the cookies. In particular the scheme should reflect whether the cookies will be sent over http, https or used in another context like javascript. The host part should reflect either the destination of the cookies or their origin in the case of javascript.

  It is up to the implementation to take into account the URI and the cookies attributes and security settings to determine which ones should be returned.

  HTTP protocol implementers should make sure that this method is called after all request headers related to choosing cookies are added, and before the request is sent.

  Parameters:

  uri - a URI representing the intended use for the cookies

  requestHeaders - - a Map from request header field names to lists of field values representing the current request headers

  Returns:

  an immutable map from state management headers, with field names "Cookie" or "Cookie2" to a list of cookies containing state information

  Throws:

  IOException - if an I/O error occurs

  IllegalArgumentException - if either argument is null
