To understand the change of the next machine variable, it is how to trigger the human-machine interface animation in one step.This step-by-step trigger is essentially a bulk data change (DataChange) event for the variable group (s), which raises the variable (TAG) value Update (ValueChange) event, which eventually triggers an animated script (Action) of the e

Question:Most firewalls or UTM deployment modes include the routing mode, the bridge mode, and the hybrid mode. The core configuration is the write rule, A good rule will greatly improve the security of the internal network. Of course, if UTM is used, other security components may be attached. For example, the most common rule is the AV anti-virus component, IPS components, anti-spam components, and some other components such as VPN, this article mainly describes the configurations of USG series
504 gateway time-out
Problem:
The requested gateway does not have a request. In short, it does not have a request for PHP-CGI that can be executed.
In general, this situation may be caused by the small buffer of nginx's default FastCGI process response, which will cause the FastCGI process to be suspended. If your FastCGI service does not handle this suspension well, in the end, 504
