X-Accel-Redirect is for the application to tell nginx to return the
content of a different (local) uri. The value should start with "/".

Nginx is a proxy server, so there are ways to map a local uri to a remote
resource, but that seems to be a side issue here:

if you want your application to send a 302 redirect, just send a 302
redirect. You'll need a valid Location: header too.

It's allowed, but it doesn't do what you hope it does.

If you look in the debug log, you'll see something like

 open() "/usr/local/nginx/htmlhttp://www.google.com;" failed (2: No such file or directory)

Good luck with it,
