    A custom Screen URL works on the module level, letting you to change how the URL of one screen shows in the browser. The Screen ProductListSection from your module can load from the URL /Products instead of /ProductListSection. Custom Screen URLs support having the parameters on the path instead of using the query string, so you can redirect users to the URL /Products/1 that would without the custom URL load as /Products?Id=1.

    The following table shows examples of custom Screen URLs:

    Original URL With Path With Query string
    /ProductListSection /Products
    /Products?Id=1 /Item/1 /Item?Id=1
    /Order?Id=1 /Buy/1 /Buy?Id=1
    /Order?Id=1&Quantity=10 /Buy/1/10 /Buy?Id=1&Quantity=10

    Make sure all Page Names are unique in the environment. Otherwise, some URLs may not work. See also: Avoiding duplicated redirects.

    See Managing custom Screen URLs for instructions.


    Redirect rules let you redirect browser requests from the old domain or subdomain to the new URLs. OutSystems uses the 301 HTTP status code for the domain-level redirects.
