I'm working under an IIS environment. I would like to put up a splash page for our site maintenance, however, the splash page (
app_offline.htm) has to be served on a separate site, since our developers still want to be working with the site while the
app_offline.htm is up.
My plan: Use URL-Rewrite to separate traffic to two groups by IP, Public and developers. For developers, "None" action is applied, for public, they will be redirected to an app_offline.htm (503) page on a separate server.
Since it is a redirect to
app_offline.htm. I'm assuming when Google robots will first pick up a 302, then pick up a 508?
Eventually does the 503 count or does only the 302 count?
I figured I had to put
app_offline on another site since it brings down the entire site and beats the purpose of separating the IPs. But any better alternative to my plan will be appreciated too.
