Block access to XML files

For example via URL: http://www.joomlasearchengineoptimization.nl/administrator/components/com_sh404sef/sh404sef.xml you will get the version information of external components. This is not verry secure.

You can easily solf this with your .htaccess file. Insert the following code in your .htaccess file and nobody can access XML files anymore:

<Files ~ "\.xml$">
Order allow,deny
Deny from all
Satisfy All
</Files>
