FortiWeb supports Lua scripts to perform actions that are not currently supported by the built-in feature set. You can use Lua scripts to write simple, network aware pieces of code that will influence network traffic in a variety of ways. By using the scripts, you can customize FortiWeb's features by granularly controlling the traffic flow or even the contents of given sessions or packets.
In FortiWeb, the scripting language only support HTTP and HTTPS policy
