I am in the process of developing a new DNN site for a client.
They had an old site but requested that the domain be referred to a url showing that a new site is under construction.
They dont want people seeing the old site while the new one is being built.
I have set up the redirect and the home page is pointing to the Under construction page as needed.
The issue i have is that previous visitors to the clients site are still being directed to the old site.
Is it possible that the old hosting site can be visible by previous client due to it being in their cache on their pc?
If so, is there a way to add a script or something so they everyone that goes to their URL will be directed to the new site landing page and not the old site?
In other words forced a refresh when opening the page?
