You should use DefaultProxyRoutePlanner if you have a single fixed proxy, SystemDefaultRoutePlanner if you want to be using the system proxy selector or a custom HttpRoutePlanner if you have a more complex request routing logic. Please also note RequestConfig#setProxy will be un-deprecated in 5.5.1 and 5.6, so you can also use it and ignore the deprecation warning for now.
