Delay action
Customers with a Bot Management and a Workers subscription can use the template below to introduce a delay to requests that are likely from bots.
The template sets a minimum and maximum delay, and delays requests where the bot score is less than 30 and the URI path starts with /exampleURI
.
// Configurable Variablesconst PATH_START = '/exampleURI';const DELAY_FROM = 5; // in secondsconst DELAY_TO = 10; // in seconds
export default { async fetch(request, env, ctx): Promise<Response> { const url = new URL(request.url); const botScore = request.cf.botManagement.score
if (url.pathname.startsWith(PATH_START) && botScore < 30) { // Random delay between DELAY_FROM and DELAY_TO seconds const delay = Math.floor(Math.random() * (DELAY_TO - DELAY_FROM + 1)) + DELAY_FROM; await new Promise(resolve => setTimeout(resolve, delay * 1000));
// Fetch the original request return fetch(request); }
// Fetch the original request without delay return fetch(request); },} satisfies ExportedHandler<Env>;
