It is also possible to require client authentication by providing a Root CA file using the
SL_NETAPP_HTTP_CA_CERTIFICATE_FILE_NAME option. If provided, all client connections are
verified, and those failing the test are not accepted. SSL client verification is described in more detail in
.

9.9.1 Processing of Parallel Requests
Each HTTP request is handled over a single TCP connection. The client initiates a connection, and sends
the request. The server processes the request and sends the response over the same connection, closing
it once sent. The server then waits to accept a new connection. Even though only one request can be
processed at any given time, many clients can initiate TCP connections to the server simultaneously, and
each request is handled in order.
