When I set up the allow_url_fopen option, it works too well, and block images/data imported via another xoops module, in my case, the "Sitka Weather" module which imports current weather data/images from yahoo. Is there a technique to use this option in protector, but add additional lines to httpd.conf that permits url access to specific url's such as this?
eg)
<Directory /path/to/the/module>
php_admin_flag allow_url_fopen 1
</Directory>
Anyway, I recommend to drop such modules depended "allow_url_fopen".
Use fsockopen()/snoopy instead of fopen("http://").
