Slow down suspicious requests

Define a delay to be used when incoming requests match a rule you consider suspicious based on the bot score.

Snippet code

export default {
async fetch(request) {
// Define delay
const delay_in_seconds = 5;
// Introduce a delay
await new Promise((resolve) =>
setTimeout(resolve, delay_in_seconds * 1000),
); // Set delay in milliseconds
// Pass the request to the origin
const response = await fetch(request);
return response;
},
};

Snippet rule

Configure a custom filter expression:

FieldOperatorValue
Bot Scoreless than10

If you are using the Expression Editor, enter the following expression:

(cf.bot_management.score lt 10)
