Avoid logging anonymous sessions

[Kailegh]

I have a Django server in aws, and there is a process that pings the index page to check the health status every few seconds. My problem is that this health check fill the user session table with non-releveant data, is there a way to avoid logging the activity of anonymous/not logged users?

Thanks a lot!
