A WSGI server that does forking.This class is identical to WSGIServer but handle each request in a new process using the ForkingMixIn. This is useful to handle web browsers pre-opening sockets, on which Server would wait indefinitely.

```python
from sl.server import make_server, ForkingWSGIServer
make_server("localhost", 8080, demo_app, ForkingWSGIServer)
```

open <http://localhost:8080> and see

you can do many requests to server.&#x20;
