Question

An external server (I’ll call it “sub.origin.edu”) redirects all traffic to my webpage. I want to take all traffic from this host, and redirect it to a different site (which I’ll call “http://foo.target.edu/board/”).

My .htaccess file is:

 RewriteEngine On
 RewriteCond     ${HTTP_HOST}    sub\.origin\.edu [NC]
 RewriteRule     ^(.*)$  http://foo.target.edu/board/ [R=302]

This doesn’t seem to be working. I’ve confirmed (using PHP) that the host is indeed sub.origin.edu, and the .htaccess file is in the right directory, but this rule just doesn’t come into effect. Any suggestions? Thanks.

(If I remove the RewriteCond, the redirect happens, so I can confirm that everything but the rewrite condition is working.)

Answer 1

Use this:

RewriteEngine On
RewriteCond     %{HTTP_HOST}   sub\.origin\.edu [NC]
RewriteRule     ^(.*)$  http://foo.target.edu/board$1 [R=302]

You used the wrong substition character ($ instead of %)
