Additional Configuration Settings 

Use

You can set and modify the following features in your Web application:

·        Alert message to be displayed on the screen, warning you that a server node running a particular Web application will be shut down.
The displayed tabs and fields correspond to the following tags in the web-j2ee-engine.xml:

<!ELEMENT fail-over-alert (message?, message-timeout?)>
<!ELEMENT message (#PCDATA)>
<!ELEMENT message-timeout (#PCDATA)>

·        The number of maximum user sessions to an application.
The displayed indicator corresponds to the following tag in the web-j2ee-engine.xml:

<!ELEMENT max-sessions (#PCDATA)>

·        The timeout period for HTTP sessions that are created in the corresponding Web application. After being inactive for the specified timeout, the HTTP sessions expire. The period is specified in minutes:

<!ELEMENT session-timeout (#PCDATA)>

You can only change the session timeout property in the application’s own deployment descriptors. This is not possible for the Global Web Descriptor.

·        If session tracking is performed using cookies or the URL rewriting mechanism. By default, the URL Session Tracking is not set, which means that cookies are used when client supports cookies, and URL rewriting in cases when client does not support cookies. If URL Session Tracking is set, URL rewriting is used in each of the cases.
The displayed indicator corresponds to the following tag in the web-j2ee-engine.xml:

<!ELEMENT url-session-tracking (EMPTY)>
