Page Redirection mechanism allows Administrator to define which page that particular user, or department or groups should access upon successful login.
This feature is out-of-the-box feature, and there's no need to change system.


For example; 

All users will redirect to main homepage. But Secretaries will access special secretary main homepage.



The above screenshot is example of data entry.
The "Source URL" is "/", which means the main homepage.
The "Redirect to URL" is "~/secretary". It means, when user access the main page (/), system will redirect the page to secretary page.

The "Group" is "Dept Secretaries". It means, this rule only applicable if the user is member of group "Dept Secretaries".
