Source code: https://github.com/Siujoeng-Lau/WorkersProxy

How to use: Modify the constants at the beginning of index.js, and then deploy it to cloudflare workers

1. Advantages:

Speed ​​up any website with Cloudflare Workers, no need to buy or configure a server

Can be used for static resource CDN. No need to connect the domain name to cf

You can block some regions or IPs based on user-agent

Can bind custom domain names

2. Disadvantages: Cloudflare Workers make 100,000 free requests a day

3. The specific source code is as follows:

// Custom domain of your WorkersProxy. const main_domain = 'https://cdn.reverse-proxy.live/' // Subdomain of your Cloudflare Worker. const workers_domain = 'https://google.xasiimov.workers.dev' // Website you intended to retrieve for users. const upstream = 'https://www.google.com/' // Website you intended to retrieve for users using mobile devices. const upstream_mobile = 'https://www.google.com/' // Countries and regions where you wish to suspend your service. const blocked_region = ['CN', 'KP', 'SY', 'PK', 'CU'] // IP addresses which you wish to block from using your service. const blocked_ip_address = ['0.0.0.0', '10.0.0.0'] addEventListener('fetch', event => { event.respondWith(fetchAndApply(event.request)); }) async function fetchAndApply(request) { const region = request.headers.get('cf-ipcountry').toUpperCase(); const ip_address = request.headers.get('cf-connecting-ip'); const user_agent = request.headers.get('user-agent'); let response = null; let url = request.url; if (device_status(user_agent)){ url = url.replace(main_domain, upstream); url = url.replace(workers_domain, upstream); } else { url = url.replace(main_domain, upstream_mobile); url = url.replace(workers_domain, upstream_mobile); } if (blocked_region.includes(region)) { response = new Response('Access denied: WorkersProxy is not available in your region yet.', { status: 403 }); } else if(blocked_ip_address.includes(ip_address)){ response = new Response('Access denied: Your IP address is blocked by WorkersProxy.', { status: 403 }); } else{ let method = request.method; let headers = request.headers; response = fetch(url, { method: method, headers: headers }) } return response; } function device_status (userAgentInfo) { var Agents = ["Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod"]; var flag = true; for (var v = 0; v 0) { flag = false; break; } } return flag; }

4. Specific configuration of index.js

The URL should be https:// // Custom domain name (leave empty if not available) const main_domain =

// Workers domain name. const workers_domain =

//The website to be accelerated. const upstream =

// Website to be accelerated for mobile users. (If not, just the same as above) const upstream_mobile =

//Regions to be blocked const blocked_region = [‘CN’, ‘KP’, ‘SY’, ‘PK’, ‘CU’]

//IP to be blocked const blocked_ip_address = [‘0.0.0.0’, ‘10.0.0.0’]
