Rewrite rules to redirect to a temporary offline page

September 22, 2010 /

Sometimes you want to take a site offline for a while. You can put this in .htaccess or the vhost config: 

ErrorDocument 503 "We are performing maintenance on the site. Check back in a few minutes."
RewriteCond %{REMOTE_ADDR} !=1.2.3.4
RewriteEngine On
RewriteRule .* - [R=503,L]

When using .htaccess, be sure to have AllowOverride All.

Or when using HTML files and images: 

<VirtualHost *>
  ServerAdmin webmaster@ytec.nl
  ServerName www.example.nl
 
  DocumentRoot /var/www/down/
 
  ErrorDocument 503 /maintenance.html
 
  RewriteCond %{REQUEST_URI} =/maintenance.html [OR]
  RewriteCond %{REQUEST_URI} =/logo.jpg
  RewriteRule (.*) $1 [L]
 
  RewriteEngine On
  RewriteRule .* - [R=503,L]
</VirtualHost>

Redirect multiple domains to one

September 7, 2010 /

When a site is available under multiple domains, it is usually bad idea to not have them all redirect to one domain. In apache, do this: 

RewriteEngine On
RewriteCond %{HTTP_HOST}   !=www.domain.com
RewriteRule ^(.*)$         http://www.domain.com$1 [L,R=permanent]
