pdf redirect

[#1]

I have a link going direct to pdf documents on one site eg www.one.com/blah.pdf. The pdf's are moving to a new web site www.two.com/blah.pdf.
These pdfs are coming up very high in Google. I was hoping if I changed them to redirects Google would follow. Also for those that have a link in their web site to these pdfs it will be broken when I move them to the new url.
I have been advised to use the htaccess method. Will this work on plusnet?

htaccess redirects definitely do work, but be aware that there are some quirks to Plusnet's platform that can break some of the common htaccess examples given on the web, so test everything that you can!

I forgot you could use "Redirect".
That's part of mod_alias I think and a lot easier than using mod_rewrite which I was thinking of.
