Step 3. Configure Advanced WebView Options for User Sessions

There are several advanced options for refining the WebView performance during a user session. You can find these options in the Advanced WebView Options dialog box.

Make sure the Web server is stopped.
Select the WebView tab on the CIMPLICITY Options dialog box.
Click Advanced.

The Advanced WebView Actions dialog box opens.

1	Start CIMPLICITY
2	Screen update settings when no user input is received
3	Allow Web server directory listing
4	No setpoints
5	Web server (HTTP) port
6	Web server root directory
7	Maximum sessions.
8	Enable auto logout

1	Start CIMPLICITY

Keep Start CIMPLICITY checked.

Note: If you clear Start CIMPLICITY you will stop the Web server from communicating with other servers that have CIMPLICITY projects in the WebView configuration. This option enables WebView developers to isolate the Web server, when necessary.

2	Screen update settings when no user input is received

(Optional) Specifies the rate at which WebView sends updates to the client when a user is not interacting with the screen, for example, clicking a button. When a user is interacting with the screen, updates come in real time.

Enter the number of seconds in:

Wait	(n seconds) WebView will continue to send updates to the client at the normal rate for the number of seconds entered in the Wait field.
Then update the screen every	(n seconds) When the number of seconds to wait have been reached, WebView will begin the specified update rate and wait the number of seconds entered in the Then update the screen every field between each update.

Note: This feature enables you to slow down the update rate. This can help reduce the load on a system by reducing the updates out to WebView if a user is not interacting with the system.

3	Allow Web server directory listing

Do one of the following.

Check

Allows Web server to list the WebPages directory contents as a default home page, when a home page does not exist.

Clear

Does not allow the WebPages directory as a default home page, when a home page does not exist.

Be sure to include a home page file in the WebPages directory or sub-directory if you leave this option blank. If a home page file does not exist, the Web server will display an error message when a client attempts to view the Web site.

4	No setpoints

Check No setpoints if you want to prohibit WebView users from performing setpoints.

5	Web server (HTTP) port

Leave the default of 80 in the Web server (HTTP) port field.

Most Web browsers expect the Web server to listen on port 80.

Notes

The Port 80 setting also applies for broadcast sessions.

If you receive an error message saying that the port is in use, either change the port for the other use or use the Web server (HTTP) port field to change this port. If you change the Web server port users will have to enter the port number in the URL address.

Example

http://server1:801/webview/index.html

Where

server1 is the Web server

801 is the port number

6	Web server root directory

Normally, use the default root directory used by the built-in Web server that displays in the Web server root directory field. Only files in this directory and in any sub-directories will be available from the Web server. If you modify the location of this directory, make sure you copy the ProwlerClient.jar file to the new location.

7	Maximum sessions

Note: Maximum sessions allows the maximum number of sessions to be fine tuned to a value less than the number of licensed connections if, for performance reasons, if you find your server can not provide optimal performance with all the licensed connections.

Enter a number of sessions that is less than or equal to the number of available WebView licenses.

When the entered number is exceeded:

A message displays alerting additional users who log on that the maximum number has been exceeded.

The connection is then lost.

8	Auto logout

You can help CIMPLICITY runtime users save resources by enabling automatic log out for a CIMPLICITY WebView user.

Automatic log out will log the user out if there is no mouse or keyboard activity for a specified number of minutes. Based on the configuration selection, the user can be logged out only, prompted to log back in or another user can be logged in.

FIll in the following checkbox and field

Check Box/Field	Description
Enable Auto logout	Check to enable auto log out.
Logout idle time	Number of minutes there is no activity (e.g. no mouse or keyboard movement) before the select auto log out option takes effect.

Select one of the automatic log out options. The following occurs if the WebView user does not interact with the WebView screen for the specified Logout idle time.
