mention_cookies (request, opts)

Places the ‘Cookie’ header in the request if appropriate.

(This method will have no effect if the EndPoint is not tracking cookies)

163: 
164:       request['Cookie'] = cs.collect { |c| c.to_header_s }.join(",")
165:     end
parse_cookies (response)

Parses the HTTP response for a potential ‘Set-Cookie’ header, parses and returns it as a hash.

76:     end
prepare_cookie_jar ()

Prepares the instance variable @cookies for storing cooking for this endpoint.

Reads the :cookies endpoint option for determining the size of the cookie jar (77 by default).
