QUESTION:
How many timeout values are present and where can I configure the timeouts for a Web Application?
ANSWER:
Visual DataFlex Web Applications Administrator has 3 timeout values you can configure globally for all Visual DataFlex webapplications. They can be found through starting the Web Application Administrator tool from either the Start Menu or the Studio. In the tool, go to the View pulldown and choose Options. Here you find the Message timeout, the transaction timeout and the Termination timeout. These three values cannot be changed from an application and are global i.e. applied to the server.
The next timeout value you can configure is loaded from the global.asa file and can be set via the Visual DataFlex Studio. Choose program properties - when you have a Webapplication opened - and on the tabpage labeled "Web Application" you will find the session timeout value. This value overrides the session timeout value that you can set via IIS and on its turn you can override this at page level (see Note-1)
IIS has three timeout values you can configure.
1. The connection timeout is per website. You can configure this value by starting IIS, selecting your website, choose properties. In the dialog that opens the tabpage labeled "Web Site" shows this configuration value.
2. The other two timeout values are per virtual directory (application). Start IIS, select your website and choose your webapplication (virtual directory) name, then via right mouse click choose properties. In the dialog that opens you can click the button labeled "Configuration". The opened dialog has the timeout values on the tabpage labeled "Options". There is session and an ASP script timeout value.
Note-1:
The session timeout can be queried and set per page if you like via the following code construction:
<%
Dim iSessionTimeOut
iSessionTimeOut = Session.TimeOut
Session.TimeOut = 5 ' Value is in minutes
%>
Rest of your ASP page
<%
Session.TimeOut = iSessionTimeOut
%>
