// =============================================================
// Basically, we can't redirect to where we were previously if it was a permalink

// Cases:
// - / : nothing in $_GET, redirect to self
// - /?page : redirect to self
// - /?searchterm : redirect to self (there might be other links)
// - /?searchtags : redirect to self
// - /permalink : redirect to / (the link does not exist anymore)
// - /?edit_link : redirect to / (the link does not exist anymore)
// PHP treats the permalink as a $_GET variable, so we need to check if every condition for self
// redirect is not satisfied, and only then redirect to /
