Hi. As stated in the question, I am trying to add a custom header from Cloudflare so that my server app (PHP) can detect if the request is made from a known bot. There is a similar, perhaps even identical question with a solution in the link below. However, this does not seem to work any more, because Transform Rules > Modify Request Header no longer has “known bots” selector, like “Modify response header” has.
So basically I would like to ask if anyone has any updated solution for this?
I actually tried that earlier, and re-tried again right now with your example, but it simply doesn’t seem to be triggering on server. I have checked while having visits from Petalbot (verified category). PHP if(isset($_SERVER['X-Known-Bot'])) log_something() ... … Nothing …
Besides, if cf.client_bot is available from “Modify Request Headers”, then why doesn’t it display in the dropdown selector? It does display under “Modify Response Headers”, which seems inconsistent.
