Set session time-out

You can set the session time-out for a erwin Mart Portal using the session configuration file. The following procedure does not apply for setting session time-out for an erwin user from a client application.

Follow these steps:

Navigate to the Mart Portal installation folder at:
```
"C:\ProgramData\erwin\Mart Portal"
```
Locate and open the MartConfiguration.properties file using a text editor such as Notepad.
Change the tokenvalidity value to set the session time-out. The default timeout value is 4 hours.
Do not modify values other than tokenvalidity. Modifying other configuration values may result in undesirable session configuration settings.
Save the file.
Restart the web server.
The updated session timeout value is applied from the next session.
