How to stop a page redirect with space level redirect enabled

[Mike McInnis]

With a space level redirect in place for a phased migration to a new instance, "pretty URL title" pages redirect as expected and most "pageID title" pages were fixed to generate a "pretty URL title" before migration.  However, some were missed and old links fail (that is, a "pageID title" page redirect ends in a "page not found" error in the new instance.

Is there a way to stop the redirect during it?  For example, in the given time window the user can enter a command to remain in the old instance.  This could allow a manual title fix on both instances to make the redirect work, such as replacing "&" with "and".

I am assuming that you are using JavaScript to redirect to the new site.  If this is the case you could change it so that they have to click a button to redirect or you could extend the time it takes to redirect so they could fix the URL.
