Sets the cookie expiration to the time `t`. The expiration time may be a false value to disable expiration or a `Time` or HTTP format time string to set the expiration date.

    # File lib/webrick/cookie.rb, line 80

      @expires = t && (t.is_a?(Time) ? t.httpdate : t.to_s)
    end

    # File lib/webrick/cookie.rb, line 94
    def to_s

      ret << @name << "=" << @value
      ret << "; " << "Version=" << @version.to_s if @version > 0
      ret << "; " << "Domain="  << @domain  if @domain
      ret << "; " << "Expires=" << @expires if @expires
      ret << "; " << "Max-Age=" << @max_age.to_s if @max_age
      ret << "; " << "Comment=" << @comment if @comment
      ret << "; " << "Path="    << @path if @path
