Extension to redirect the user after login into the previous page.

Functionality:
When the user clicks the login button on the header from any page, then the login page will load as usual and after login, it will redirect to the same page where the customer clicked the login.
In this case, if there is no previous URL or direct Login, then the extension will redirect to the home page.

Code

Extend the function”Redirect in the LoginRegisterview for implementing the feature.
