First you need to make sure mod_rewrite is loaded. This line should be uncommented in your httpd.conf:
LoadModule rewrite_module modules/mod_rewrite.so
Then you can use these rules:
RewriteEngine On
RewriteCond %{QUERY_STRING} (^|&)thiscontent=2660(&|$)
RewriteRule ^/?applications/newWeb/www/index\.php$ http://www.example.come/index.php/publications/finance-and-economics/departmental-resources? [L,R=301]
And yeah, you'll need to setup each one specifically, so you'll need 30 of those (but only need RewriteEngine On
once. You can also put these rules in an htaccess file in your document root.
