# Mappings and rigths management
As you have already seen in chapter System Mappings, we use a mapping for the readable URLs, which runs through the database. Here you can find out how it is structured.
The relevant function for the mappings is the *getSEF()* function, which is called in application.cfc. In it, we resolve the URL and redirect the user to the right page.
* strMapping is the url string in the browser
* strPath is the corresponding file which is loaded by saaster
* The three “admin” columns are for the right management
We currently only operate a small rights management system in saaster, which is reduced to the individual pages. Depending on the status of the logged-in user, the pages are blocked or can be accessed.
If all three boolean values are set to 0, a normal user can also call up the page
