Warning: Super user account!

When Working on a farm environment couple of time we come across some warning stating:
"The super user account utilized by the cache is not configured...."

Temporary Solution :: execute- 'stsadm -o setproperty -propertyname portalsuperuseraccount -propertyvalue account -url webappurl'.

Furthermore, there is the caveat:
The account should be any account that has Full Control access to the SharePoint databases but is not an application pool account. What have people done - create a special account?

After doing an extensive research i found solution as stated by Mirjam van Olst
