RewriteRule doesn't work Due to request, every page (except the front page) needs to be prefixed with "training"; if the path was first /aboutus, now it needs to be /training/aboutus.

I edited almost every page I needed by rewriting mypage.tpl.php, so to change all path would be troublesome.

I tried to edit the .htaccess file, for example using the following rewrites. 

RewriteRule ^/training/about$ /about




RewriteRule ^(.*)/training/about$ $1/about


Neither of them works.

Could someone point me to the right direction?
Using rewrite in .htaccess may change how external URLs are handled by Apache, but it won't change how Drupal generates URLs itself. For that you need to change the base URL. Take a look at https://stackoverflow.com/questions/5879190/how-to-set-the-base-url-in-drupal
