Redirecting all http/s request to custom page, if internet is not avaiable.
it it possible to redirect all http and https requests to a custom error page if the internet is not available?
thank you in advance.
I do not have a solution but I would be also interested in one.
This redirect could happen if for example a request could not be resolved within 5s or 10s.
I am interested in this, too, when doing maintenance on an upstream router so that the users know that what is going on.
