> With DefaultHttpClient it is not difficult to use a custom DNS resolution strategy (e.g., DNSJava) by using a
> specialized DefaultConnectionOperator. Doing the same with the asynchronous client presently is very difficult as it requires to create an entirely new connection manager (and the standard implementation uses many package-accessible implementations, so this requires modifying the actual HttpAsyncClient distribution). For a client able to open simultaneously thousands of connections careful DNS management is essential.
> Of course it is in principle possible to use a local installation of BIND etc., but it would be nice to be able to do configurable DNS caching in pure Java.
