0N/A * Test Description:
0N/A * - main thread run as a http client
0N/A * - another thread runs a http server, which redirect the first call to "/redirect"
0N/A * and return '200 OK' for the successive call
0N/A * - a global ResponseCache instance is installed, which return DeployCacheResponse
0N/A * for url ends with "/redirect", i.e. the url redirected to by our simple http server,
0N/A * and null for other url.
0N/A * - the whole result is that the first call will be served by our simple
0N/A * http server and is redirected to "/redirect". The successive call will be done
0N/A * automatically by HttpURLConnection, which will be served by DeployCacheResponse.
0N/A * The NPE will be thrown on the second round if the bug is there.
