Refresh Prompts while navigating Dashboard Pages

Again came up with a new requirement and thought of sharing the same with you. My client asked me to wipe out the selected values in the Dashboard prompts when he navigates from one page to another on the dashboard.
So, finally I found the following solution for the same.
We need to add a tag in the instanceconfig.xml file to achieve this. Stop the presentation services and place the below given tag in instanceconfig.xml
<PersistPageState>FALSE</PersistPageState>
The tag can be placed anywhere between the server instance tags in instanceconfig.xml.
Start the Presentation services and login into the application and check by setting some values in the prompts.
