I wanted to redirect mydomain.com to www.mydomain.com. Furthermore I have other domains set as co-domains in ISPConfig2. Therefore I wanted to have all these co-domains (mydomain.net; mydomain.info; mydomain.eu etc.) redirected to their respective equivalents (www.mydomain.net; www.mydomain.info; www.mydomain.eu etc.) . The solution for this is simple. Put following code into Apache Directives field: Code: RewriteEngine On RewriteCond %{HTTP_HOST} !^www RewriteRule (.*) http://www.%{HTTP_HOST}$1 [L,R] Afterwards each domain will redirect to its respective www.domain.tld Thanks developers for such excellent tool as ISPConfig!
