  - setConnectTimeout
```
public void setConnectTimeout(int timeout)
```
  - setReadTimeout
```
public void setReadTimeout(int timeout)
```
    Sets the read timeout. Note: Public URLConnection (and protocol specific implementations) protect against negative timeout values being set. This implementation, and protocol specific implementations, use -1 to represent the default read timeout. This method may be invoked with the default timeout value when the protocol handler is trying to reset the timeout after doing a potentially blocking internal operation, e.g. cleaning up unread response data, buffering error stream response data, etc
