Webserver built for my specific needs.

Not intended for public use!

All I really need is to serve some files based on what subdomain is requested, and maybe some reverse proxying.

No need for all the fancy schmancy configuration options of a real web server when I can get away with a tiny Go project to cover the same needs.

DO NOT base any of your own work on this, as it will change without notice as my needs change. Fork instead.

I only provide this to others for educational purposes, and do not suggest you will actually use it for serving files publically. For that, I hope it's instructional enough to be of value.

My needs

The needs I identified before starting the project:

• Serve static files based on what subdomain is requested.
• Minimal configuration.
• Easy to modify trumps any performance concerns: I don't need it fast!
• Reload the certs when certbot renews them, with no interaction needed for me.
• Somewhat similar proxy passing as nginx proxy_pass directive.

Example configuration

The example configuration does roughly this:

1. Listen on port 80, redirecting all requests there to the same host and path, but port 443.
2. Listen on port 443, preparing to serve HTTPS requests there.
3. Log most stuff to /var/log/tjenare.log
4. For requests to example.com...
   1. Load the cert /etc/letsencrypt/live/example.com/fullchain.pem and with the key/etc/letsencrypt/live/example.com/privkey.pem
   2. Get the subdomain, or use www if one is not specified.
   3. Check if the subdomain is defined as a backend and act as a reverse proxy if it is.
   4. If not spork, serve the requested file, out of /var/www/html/{subdomain}/public_html/

Some examples of requests and where they'll try and read from, given the example configuration:

• https://foo.example.com/bar.png = /var/www/html/example/foo/public_html/bar.png
• https://example.com/plop.html = /var/www/html/example/www/plop.html
• https://horse.example.com/plop/ = /var/www/html/example/horse/plop/index.html
