12
13    ``app``

28
29    ``ssl_pem``
30
31        This an optional SSL certificate file (via OpenSSL) You can
32        generate a self-signed test PEM certificate file as follows:
33
34            $ openssl genrsa 1024 > host.key
35            $ chmod 400 host.key
36            $ openssl req -new -x509 -nodes -sha1 -days 365  \\
37                          -key host.key > host.cert
38            $ cat host.cert host.key > host.pem
39            $ chmod 400 host.pem
40
41    ``protocol_version``
42
43        The protocol used by the server, by default ``HTTP/1.1``.
44
45    ``numthreads``
46
47        The number of worker threads to create.
48
49    ``server_name``
50
51        The string to set for WSGI's SERVER_NAME environ entry.
52
53    ``max``
54
55        The maximum number of queued requests. (defaults to -1 = no
56        limit).
57
58    ``request_queue_size``
59
60        The 'backlog' argument to socket.listen(); specifies the
61        maximum number of queued connections.
62
63    ``timeout``
64
65        The timeout in seconds for accepted connections.
