Network Security Considerations
-------------------------------
Keep in mind that 0x0 can fetch files from URLs. This includes your local
network! You should take precautions so that this feature cannot be abused.
0x0 does not (yet) have a way to filter remote URLs, but on Linux, you can
use firewall rules and/or namespaces. This is less error-prone anyway.
For instance, if you are using the excellent `FireHOL <https://firehol.org/>`_,
its very easy to create a group on your system and use it as a condition
in your firewall rules. You would then run the application server under that
group.
