Security Issues
Access to the application
Due to its nature, Click-Unit can consitute a security problem. Click-Unit essentially serves as a sort of proxy forwarding http requests to any web server and returning the response to any client.
Obviously running Click-Unit on a publically accesable URL is a major security issues. Steps should be taken to avoid that Click-Unit should be used as a public "proxy".
Warning
It's strongly recomended that all access to the Click-Unit only be
allowed from localhost. This can be done with the use of a firewall or
via the configuration of the web container.
