Hello, what is the easiest way to use workers to effectively define a custom set of rules before proxying a request? I'm not sure if there is a pre-built setup for this or if it's just a manual proxying of the data required.

I wouldn't recommend using a worker due to pricing, if the logic very simple, you can use the normal WAF (https://developers.cloudflare.com/ruleset-engine/rules-language/), or a Snippet (https://blog.cloudflare.com/cloudflare-snippets-alpha/, coming soon™️)

Otherwise, just return a 403 from the worker, there is no "proper" way.

I'm not sure how much we can do with WAF as we want some additional advanced logic

but price is not an issue for workers 😅 At least not compared to the cost we pay currently
