Okay so, I have an old domain that I've redirected to my new site. But now I want to redirect my old forums to my new forums. How might I do that?
How are you actually redirecting the old domain? Are both domains pointing to the same server/directory, or do you use some kind of script or htaccess to redirect?
Are you saying that you want to do something like send http://www.youroldstuff.com/forums to http://www.yournewstuff.com/forums or do you want to redirect each specific entry? Either way, maybe you should consider just adding the server alias(es) of your old domain to the web server configuration for your new site, then alter your DNS to point the old domain to your new IP address? If you don't want duplicate content across the two domains then could use mod_rewrite in Apache (or isapi filters in IIS I believe, although I have never done that) to establish redirect rules so that it will redirect to the new url with the appropriate url parameters passed as well.
