Rewrite URL in htaccess to hide certain characters

[Mattrpm]

Hi guys
I have a problem and also lack the understanding to put this rewrite rule in place.
I only need to remove these characters from any URL on our website ?rid=

from this:
example.co.uk/coffee/?rid=A611F4

to this:
example.co.uk/coffee/A611F4

The first section is created by wordpress example.co.uk/coffee/
and last part is created by an Xmpie system ?rid=A611F4
the 6 digit number is dynamic and specific to making the webpage personalised to them.
I have been told by Xmpie support that this can be done in the wordpress .hatches

We use apache and Wordpress.
The code I have in my .htaccess file on our apache server is this.

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

is it possible to show me the process as i lack experience

Really appreciate some help on this

Kind Regards
Matt

Hello,

The URL noted in the previous post is a good place to start.

Thanks!
