DWebPro provides an API that enable you to control the behavior of the application with great precision.

This API is available through HTTP requests and includes:

• Shutdown: /dwebpro/shutdown

• Lock CD: /dwebpro/lockcd

• Unlock CD: /dwebpro/unlockcd

• Start: /dwebpro/start

The shutdown API begins the DWebPro shutdown procedure and requests only the file parameter, which is the full path of the file that DWebPro displays. The following is an example of how use the shutdown API:

http://127.0.0.1:8080/dwebpro/shutdown?file=%23%23DWEBPRO_DOCUMENTROOT%23%23%5Cmyshutdown.htm

The lockcd and unlockcd APIs enable you to lock and unlock the driver in which the CD/DVD of DWebPro is running. Both the these APIs request two parameters:

• bad – Identifies the full URL that DWebPro displays if the lockcd or unlockcd execution is not successful.

• good – Identifies the full URL that DWebPro displays if the lockcd or unlockcd execution is successful.

The following is an example of how use the lockcd API:

http://127.0.0.1:8080/dwebpro/lockcd?bad=http://127.0.0.1:8080/error_locking.htm&good=http://127.0.0.1:8080/locking_completed.htm

Keep in mind that the URL should not contain spaces or carriage returns.

The Start API enables you to start an external software application using a hyperlink. The following is an example of how use the start API:

http://127.0.0.1:8080/dwebpro/start?file=notepad&params=c%3A%5Cautoexec.bat

The file field identifies the path to the executable while the params field specifies the parameters to send to the software. DWebPro start the external software using the ShellExecute Windows API.

If you need to use the DWebPro constants, keep in mind that you must encode them otherwise their values will be never sent to the server.
