POST data lost when using .htaccess

Question

I have this .htaccess file who does some redirecting and rewriting (removing extensions .. etc) but when i send data using the POST method it gets lost along the way.

tried adding this condition to stop Request with POST data from redirecting but it's not working.

Options +FollowSymLinks
RewriteEngine  On

Here's what my post request looks like

and this is the code in my destroy_session.php file

if(isset($_POST['action']) && $_POST['action'] == 'logout'){
   session_unset("username");
   session_destroy();
}

That's the actual issue here, this not related to the URL rewriting.

PHP is not going to populate $_POST, if you send a raw request like that. You need to send application/x-www-form-urlencoded or multipart/form-data.
