cURL gives Access denied: follow redirect to /public/

Question

I'm running an apache web server on ubuntu server 12.04 LTS.

If I try to

/usr/bin/curl http://mysite.com/script.php 

I get the error message

Access denied: follow redirect to /public/

What can cause this, and where should I start looking?

I'm so lost:)

One thing that bugs me and I don't understand is, where does /public/ come from? The script has no redirect.

The server is behind a firewall that I unfortunately don't have any control over. But everything else seems to be working so I don't think it's the firewall either, but that's just me guessing basically. On the web server itself, mod-security is installed. But disabeling mod-security doesn't do any difference.

This is output I got from a opencart developer when trying to figure out why the extension didn't work.

Isn't the script.php located in /public/?

Could it be that your user running the Apache does not have read access to /public/ folder?

It's hard to say what might forward you to /public/ without knowing what script.php do, and how the apache server is configured.
