httpd.conf or php.ini block full url?

[hanpedro]

At php or html, the link - http://test.com/test/test2/test.img - could not work.

SHows only "http://test.com/test/test2/test.img" as url code, or shows error message - not object , or page.

Is there some problem on configuration of apache or php?
If then, is possible to solve this problem without changing url_fopen=off?

This is httpd-vhosts file.

<VirtualHost *:80>
ServerAdmin [e-mail]
DocumentRoot K:/_web/test
ServerName testers.wowdns.com
ServerAlias www.testers.wowdns.com
php_admin_flag allow_url_fopen On
ErrorLog K:/xampp/Apache/logs/testers_error_log
CustomLog K:/xampp/Apache/logs/testers_access_log combined
</VirtualHost>

Any comments would be appreciated.
