Been working on a solution to remove odd query strings from pages after search engines keep adding them at random. I have a solution that semi works, but I would ideally like to see it clear them all. Right now the code I have is this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{QUERY_STRING} ^(.*)&?sort=[^&]+&?(.*)$ [NC]
RewriteRule ^/?(.*)$ /$1?%1%2 [R=301,L]
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{QUERY_STRING} ^(.*)&?order=[^&]+&?(.*)$ [NC]
RewriteRule ^/?(.*)$ /$1?%1%2 [R=301,L]
</IfModule>

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{QUERY_STRING} ^(.*)&?m=[^&]+&?(.*)$ [NC]
RewriteRule ^/?(.*)$ /$1?%1%2 [R=301,L]
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{QUERY_STRING} ^(.*)&itemid[^&]+&?(.*)$ [NC]
RewriteRule ^/?(.*)$ /$1?%1%2 [R=301,L]
</IfModule>

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{QUERY_STRING} ^(.*)&amp[^&]+&?(.*)$ [NC]
RewriteRule ^/?(.*)$ /$1?%1%2 [R=301,L]
</IfModule>

I am very open to suggestion to clean things up and make a much more optimized solution.

thanks in advance!
