Yes, the browser generally won't intepret it ...unless you can control the
entire target of the redirect, in which case you may be able to get the
browser to stop trying to follow the redirect and just display the content
of the page by either having the redirect point to the same URL that is
issuing it, or have a loop of redirects that end up back at the same URL
at the same time the browser runs into its maximum-number-of-redirects
limit.
Yes, definitely browser specific.
