Redirection Subdomain site/blog to another Subdomain site/blog

Would like to redirect subdomain to another subdomain in the same network

[calvinmicklefinger]

I would like to do a 301 redirect to send visitors to a different subdomain than the one they have attempted to reach. I tried to use the Wordpress plugin "Redirection," but I could not get it to work.

As an example, I would like a visitor who is sent to blog/site http://12345.mysite.com to be redirected to http://45678.mysite.com

I have tried the Redirection plugin and the WPMU Domain Mapping plugin. I could not get Redirection to work, and I did not understand how to set up the CNAME thing with the Domain Mapping plugin. (I don't even know what a CNAME is.)

Any help you can give me is appreciated!

Copying from one of the 8000 WebmasterWorld Apache forum posts which shows what to do:

RewriteEngine On
#
RewriteCond %{HTTP_HOST} ^other\.example\.com 
RewriteRule (.*) http://www.example.com/$1 [R=301,L]

Use example.com in the forum to supress URL auto-linking.

Doesn't seem to work in my install of WP 3.2.1

You need to put it above the Begin Wordpress/End Wordpress directives.
