```
public abstract class SimpleHttpExchange
extends Object
```
This class is a simplified implementation of HttpExchange.
This class provides methods to process requests from the client and send a response back. The handler will keep executing until a response is sent.

Get/post type requests for application/x-www-form-urlencoded (default) will be a simple key/value map.
Get/post type requests for multipart/form-data will use a MultipartFormData.
If a file is submitted the value will be in bytes unless it is plain text.

Since:

02.00.00

Version:

4.0.0
