Right off the bat I can already see the need of setting up a private server due to the second requirement (ability to remove HTTP header). I had an option to drop Netlify by building the pages on my workstation and deploy to the web server (using a Hexo deployer plugin). So far I do find Netlify service to be reliable and it offers features like adding headers and reverse proxy which are easy to setup. Speaking of Netlify's features, I then had an idea of setting up a web server which reverse proxy to Netlify. This approach meets all the four requirements; a side-benefit is that if I screw up the web server, at least my website is still up on curben.netlify.com and I can easily migrate this domain to Netlify.

As for web server, I went with Caddy, which has the most secured defaults. It is installed in NixOS, which is attractive for its centralised configuration. I initially planned to use Ubuntu, and then I noticed [NixOS](https://nixos.org/); unlike most other Linux servers which has configs scattered around, NixOS is configured through a single "configuration.nix" file. It is [declarative](https://en.wikipedia.org/wiki/Declarative_programming), meaning you simply supply the desired configuration and NixOS would figure how to achieve that. For example, to open port 80, you just need `networking.firewall.allowedTCPPorts = [ 80 ]`, instead of mucking around with iptables. This significantly helps reproducibility, making server migration much easier; simply supply the "configuration.nix" used in the previous server and the new server would have the same state. Having Caddy in the repo is the tipping point that finally made me dive into NixOS.

Above diagram shows the architecture behind this website (mdleom.com). When a visitor browse mdleom.com, it will first go through Cloudflare CDN, the CDN then pass the request to my virtual private server (VPS). Before it reaches my VPS, there is a cloud firewall provided by the VPS host which I configure to allow inbound port 443. Once my VPS receive the request, the iptables port forward from 443 to 4430. The web server (Caddy) binds to (or listens on) port 4430 and it acts as a reverse proxy to the actual backend, curben.netlify.com.

The flow is slightly different when browsing via [.onion](http://xw226dvxac7jzcpsf4xb64r4epr6o5hgn46dxlqk7gnjptakik6xnzqd.onion). Tor hidden service is able to NAT-punching, only rely on outbound connection, so it can work behind a firewall that block inbound ports. The Tor daemon acts as a reverse proxy and forward the request to Caddy, which in turn is also a reverse proxy which finally forward the request to curben.netlify.com.

A thing to note about I2P is that, while inside its network, you can only browse *.i2p websites, not normal websites or what is so-called the _clearnet_. This is unlike Tor where you can browse .onion and clearnet, which is routed through _exit relays_. You could browse the clearnet from I2P network by using a _outproxy_, which works similarly to exit relay of Tor. However, I2P user is discouraged from using a outproxy as that would compromise the user's anonymity.

For this website, I2P network only applies to the traffic between visitor and my (Caddy) web server, as shown in the following diagram; a request still needs to get passed to the upstream curben.netlify.com, but Netlify only sees the request comes from my web server as if it's just a regular visitor and shouldn't know that its origin from the I2P network.

The main reason for me to have a Tor hidden service is so that visitor can visit my website (mdleom.com) anonymously. Visitor indeed can browse this website _somewhat_ anonymously via VPN, but it's not hidden from the VPN provider. Even with Tor, the traffic still needs to get out from the Tor network to the Internet via exit relays, and exit relays can [do whatever](https://doi.org/10.1007/978-3-319-08506-7_16) they want to the traffic. Tor hidden service ensures the traffic is end-to-end encrypted and stays inside the Tor network--without involving any exit relay.

Note that this only applies to the traffic between visitor and the (Caddy) web server, as shown in the following diagram; a request still needs to get passed to the upstream curben.netlify.com, but Netlify only sees the request comes from my web server as if it's just a regular visitor and shouldn't know that its origin from the Tor network.
