All these URLs are missing the trailing "/index.html" or whatever other file the link should point to.

This is not a problem at the server end, if the server has been configured to serve up index.html or a directory listing by default when a filename is missing.

However, it is bad practice to rely on the default (or configured default) behavior of a specific server as it may not be the same even across identical servers.

hi Dr. Klahn

The problem in all of this url is that im calling records that I got in a wordpress blog in the same server.

At the begininng of any of this files I got this code:
<?php
define(‘WP_USE_THEMES’, false);
require('/blog/wp-blog-header.php');
?>

If I remove this code suddenly this url are not broken any more

Did anyone knows why the problem is that code?????
