Redirect-problems!

Hi!

One of my clients has asked me to redirect the traffic from their old website, to a new one which I have created.

The only problem is, that neither of us have the login-info for the old page, so we can’t get access to .htaccess or anything – the former developer is rather crossed that my client switched to me and he won’t give us the access-codes. The former developer also owns the domain – and my client don’t want to lose potential members and customers.

So, my question is – does a plugin exist, that can do a redirect WITHOUT access to original page? – Or maybe a hack?
