Static resource loading deadlock problem

clipboard.png
websites co-exist with http and https, but some users access static resources that are constantly requesting. As a result, the browser keeps turning around and cannot load it. Moreover, it appears randomly, sometimes it is another css or png image. If there is a browser cache, it can be loaded. What is the reason for this?

based on my experience of being cheated for many years:

  1. the firewall above the computer room limits the number of connections, concurrency, and so on. In particular, there are many misjudgments and injuries in some domestic low-end anti-DDoS firewalls.
  2. The
  3. server enables some speed and current limits, such as iptables.
  4. this may happen if your nginx adds modules or enables some functions, such as limit module, third-party waf module, etc.
  5. if the configuration is improper and static resources are processed by phpfpm through fast-cgi, that may be the reason for php.

1 is more likely. Grab the package and take a look. If the TCP handshake fails, it is very likely to be 1

.

I find it strange that https supposedly blocks access to http resources by default. How can you load it in https or do you adapt to different protocol resources?


but this is not the case with https
