Default Timeout

The default timeout is infinite.

By default RestTemplate uses SimpleClientHttpRequestFactory and that in turn uses HttpURLConnection.

By default the timeout for HttpURLConnection is 0 - ie infinite, unless it has been set by these properties :

-Dsun.net.client.defaultConnectTimeout=TimeoutInMiliSec 
-Dsun.net.client.defaultReadTimeout=TimeoutInMiliSec
