Redirect http requests to a new folder with apache rewrite rules
When you reorganize the structure of a website, you might want to redirect requests to files in a old folder to a new one without loosing the pagerank. In this example, I will redirect all requests from directory “olddir” to directory “newdir”, so that requests like http://www.yourdomain.tld/olddir/page.htm get redirected to http://www.yourdomain.tld/newdir/page.htm without loosing the Google pagerank of the pages.
The following rewrite rules can be added into a .htaccess file in the website directory or in the vhost configuration.
RewriteEngine on
RewriteRule ^olddir/(.*)$ newdir/$1 [R=301,L]
This rewrite rule redirects automatically all requests to pages or subdirectorys of “olddir” to the same page or subdirectory in “newdir”.
Redirect a subdomain with apache mod_rewrite and keep the URL in the address bar
If you want to redirect a subdomain like sub.domain.tld into a subdirectory of the website and keep the original URL in the browser location bar, you may use the following apache directives.
RewriteEngine on
RewriteCond %{HTTP_HOST} ^sub.domain.tld [NC]
RewriteRule ^/(.*)$ /sub/$1 [L]
This rewrite rule can be added into a .htaccess file in the website root or inside the vhost file. If you use ISPConfig 2 or 3, you can add this also into the apache directives field in the website settings.
Replace sub.domain.tld with the subdomain that shall be redirected and /sub/ with the path to the directory were the pages for this subdomain are located.
Redirect domains without www (e.g. domain.com) to www.domain.com with apache rewrite rules
If all your visitors shall access your website with a URL like www.domain.com and not without www, use the following apache rewrite rule for redirecting them.
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www
RewriteRule (.*) http://www.%{HTTP_HOST}$1 [L,R]
The apache rewrite rule can be added in a .htaccess file in the website root directory or if you use ISPConfig 2 or 3, you can also add the rwrite rule into the apache directives field of the website.
