1. SEO friendly URLs and non-www URLs
While using SEF Plugins with Joomla, one of the common issue encountered is that the default urls are without www i.e. http://example.com (assuming that Joomla is installed in the root domain)
This might irritate webmasters causing duplicate url indexing
Solution:
a. Change your Live Site URL to http://www.example.com
Download the config file “configuration.php†and edit the variable $mosConfig_live_site value to set it to http://www.example.com.
This will cause all base URL to change to http://www.example.com, hence all your internal page urls would be linked through urls with www
b. Use htaccess/Mod_Rewrite to redirect your domain http://example.com to http://www.example.com
Here is how
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
