What is the issue you’re encountering

I added the following security rule: (http.request.full_uri wildcard r"*://livestrue.xyz/ads.txt") or (http.request.full_uri wildcard r"*://www.livestrue.xyz/ads.txt"), and checked Skip all WAF components. Is this wrong? Even if I clear the specified URL cache, I access my ads.txt again, it still returns a 304 response code How should I make it return a 200 status code? (Strangely, my other requests all have a 200 response code) I set this rule mainly to deal with the review of Google Ads. But it seems to be ineffective
