SYMPTOMS
Running a Collaboration Data Objects (CDO) application in an Active Server Pages (ASP) page, may return the following error from the Internet Information Server (IIS) server:
ASP 0115
CAUSE
This is sometimes caused by not properly closing a CDO session from within an .asp application environment.
RESOLUTION
Make sure that you close all of the currently open CDO sessions that you are using. Following are two ways to do this:
- Make sure that you call the Logoff method of the Session object and set all CDO object references to Nothing immediately after the script that does the CDO operations ends. This ensures that the references are cleaned up properly.
-or-
- Use the Session_OnEnd event subroutine in the Global.asa file to ensure that all CDO Session objects are logged off and set to Nothing.
MORE INFORMATION
The Global.asa file provides the Application and Session objects with the location to run script for their OnStart and the OnEnd events.
The Application_OnStart event fires when an .asp page is requested from the application directory for either the first or the last IIS restart or application timeout. The Session_OnStart event fires when a new page is called that is not involved with the current active session, good for creating user specific variables and objects. The Session_OnEnd event is triggered when the Session timeout period has expired or a session is abandoned. The default timeout value is 30 minutes. The Application_OnEnd event is triggered when the last session is closed or the application is closed.
