How to remove ?doing_wp_cron from my URLs

I'm finding this string appended to the end of my URLs sometimes: ?doing_wp_cron

It's a sign that you have ALTERNATE_WP_CRON defined in your wp-config.php

In order to do some background processing (like publishing scheduled posts), WordPress redirects you to the URL with ?doing_wp_cron appended.
  
Remove the line from wp-config.php (although that might stop cron from working).

To Solve this manage redirection in the .htaccess file.

Here is an exemple on how to redirect the url by adding these lines in the .htaccess file :

<IfModule mod_rewrite.c>
    Options +FollowSymLinks
    RewriteEngine On
    RewriteCond %{QUERY_STRING} (^|&)doing_wp_cron= [NC]
    RewriteRule (.*) /$1? [R=301,L]
</IfModule>

Hope this will help !
