Hi, We are changing one of our domain names which has about 150 host/subdomains. Apache version is 2.0.52 on RHEL4 Current http_host's would look something like this: service1.old-domain.com service2.old-domain.com host1.subdom1.old-domain.com etc... I need to make them read: service1.new-domain.com service2.new-domain.com host1.subdom1.new-domain.com >From what I can see I would need to add a separate rewrite set for each host within the old domain: RewriteCond %{HTTP_HOST} ^service1\.old-domain\.com$ [NC] RewriteRule ^(.*)$ service1.new-domain.com$1 [R=301,L] RewriteCond %{HTTP_HOST} ^service2\.old-domain\.com$ [NC] RewriteRule ^(.*)$ service2.new-domain.com$1 [R=301,L] etc... I am searching for a method to do this with a single rule. I have tried adding shell type variable substitution but that fails: OLDDOM=%{HTTP_HOST} NEWDOM=`echo %{HTTP_HOST}|sed s/old-domain/new-domain/` RewriteRule ^(.*)$ ${NEWDOM}$1 [R=301,L] Any help would be appreciated.
