I have www.mydomain.com and www.mydomain.com.au Both these domains also work without the "www". I'm trying make it so: -www.mydomain.com -www.mydomain.com.au -mydomain.com -mydomain.com.au all rewrite to "www.mydomain.com.au" Everything works except rewriting www.mydomain.com to www.mydomain.com.au My .htaccess : RewriteCond %{HTTP_HOST} ^mydomain.com.au [NC] RewriteRule ^(.*)$ http://www.mydomain.com.au/$1 [L,R=301] RewriteCond %{HTTP_HOST} ^mydomain.com [NC] RewriteRule ^(.*)$ http://www.mydomain.com.au/$1 [L,R=301] RewriteCond %{HTTP_HOST} ^www.mydomain.com [NC] RewriteRule ^(.*)$ http://www.mydomain.com.au/$1 [L,R=301] Code (markup): Please tell me the obvious mistake that I'm making. Whenever I add the last 2 lines it screws up and my site point nowhere. And also, will this actually benefit my Google ranking/pagerank? I just can't get my head around htaccess, no matter how much I try
