.htaccess redirect if ANY query string is present?

Question

I have the following .htaccess at present.

 suPHP_ConfigPath /home/abc/php.ini


RewriteEngine on
RewriteCond $         


        

Answer 1

The following should work:

RewriteCond %{QUERY_STRING} .
RewriteCond %{REQUEST_URI} !^/index.php
RewriteRule ^ /index.php/? [L]

1. check if you've got something in QUERY_STRING (yours also accepts an empty string)
2. your check to prevent endless redirect
3. redirect to wherever you want.

From the Apache documentation:

When you want to erase an existing query string, end the substitution string with just a question mark

EDIT (again): As external redirect (you may not even need the second RewriteCond if you don't have any query string at all in your application):

This will tell the client to request the same URI without query string.

RewriteEngine on

# redirect to same URI, but without query string
RewriteCond %{QUERY_STRING} .
RewriteRule ^ %{REQUEST_URI}? [R=301]

# CodeIgniter "magic"
RewriteCond $1 !^(index\.php|media|css|js|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
