something in each request with CDN

[Saeeed-B]

Hi, considering that CDN does not send the request to the server,
If I want to do something in each request, for example, to save a series of statistics in the database or to check the request header, what should I do?

It depends on what you want to do... e.g. a simple header check can be implemented using the nginx if directive, or nginx auth_request.
If you need something more complex, you can use nginx-lua to write custom Lua code in various phases of the request (e.g. access_by_lua_block)

Well, the point is that cdn does not transfer the request to our vod server in every req . And response himself
