Redirect rules in Saurus CMS

  1. Your web server should have Apache URL Rewrite Engine module (mod_rewrite), most servers do.
  2. Set up rewrite rules for aliases as guided on page www.saurus.info/configuring-alias-module
  3. Include redirecting rules before alias rules, that's the only way Saurus CMS aliases keep working

Example of alias rerwite rules together with redirecting rules in .htaccess file:

Options +SymLinksIfOwnermatch 

RewriteEngine on 
RewriteCond %{HTTP_HOST} ^yoursite\.com$ [NC] 
RewriteRule ^(.*)$ http://www.yoursite.com/$1 [R=301,L] 

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d 
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME}  !^/admin 
RewriteCond %{REQUEST_FILENAME} !^/classes 
RewriteCond %{REQUEST_FILENAME} !^/editor 
RewriteCond %{REQUEST_FILENAME}  !^/extensions 
RewriteCond %{REQUEST_FILENAME} !^/idcard 
RewriteCond %{REQUEST_FILENAME} !^/js 
RewriteCond %{REQUEST_FILENAME}  !^/public 
RewriteCond %{REQUEST_FILENAME} !^/px 
RewriteCond %{REQUEST_FILENAME} !^/px_custom 
RewriteCond %{REQUEST_FILENAME}  !^/shared 
RewriteCond %{REQUEST_FILENAME} !^/styles 
RewriteRule ^/(.*) /map.php?mod_rewrite=/&cmd=$1  [L,PT,QSA] 

# RewriteLogLevel 0 will disable logging, we suggest set it to 2  
# for debugging problems 
RewriteLogLevel 0 

# set correct log file path  here, we suggest set it only when debugging problems: 
# RewriteLog  /var/log/httpd/rewrite.log
