This will serve as a step-by-step guide for creating a URL shortener with Cloudflare Workers. The project is a fork of Atomic URL by Jerry Ng, although I've heavily modified it to suit my needs.
In addition to leveraging Cloudflare Workers, this project will also leverage the following...
Because I use Cloudflare to manage my domains and Backblaze for backups, it only made sense to take advantage of their Bandwidth Alliance for creating my own CDN. This has been incredibly helpful for image hosting for this knowledge base, however, I recently noticed that caching wasn't working as it should.
The overall problem started when I was adding a parking page for a domain I recently purchased. The background image was hosted on B2 and the image was supposed to be cached by Cloudflare. However, each time the page loaded, it would pull the image from the origin instead of the cache. I checked this on my knowledge base and found it was doing the same thing.
While the article from James Ross is solid and works very well with images, I found it fell short with any streaming video with the Bandwidth Alliance (to be fair, the article mentions nothing about videos, only images). Although the URL was being rewritten, it didn't seem to be handling video properly and even short videos were taking a long time to load.
That being said, the following seems to work perfectly...
Note: None of this code is mine. I'm basically standing on the shoulders of giants.
index.js file:
| # to generate your dhparam.pem file, run in the terminal | |
| openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048 |
No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.
Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.
