Answer 1

The rule need is this:

 RewriteEngine On
 RewriteBase /

 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteRule ^cpanel/([^/]+)/?$ def.php?p=cpanel&m=$1 [L,QSA,NC]

Reference: Apache mod_rewrite Introduction

• RewriteCond %{REQUEST_FILENAME} !-f means iif request is not for a valid file
• $1 is backreference to captured string after /cpanel/
• QSA (Query String Append) flag preserves existing query parameters while adding a new one.
• NC is for ignore case
• L is for Last rule
