This is a small program that acts as a proxy server for my websites. You can point multiple hostnames at one IP address, and once configured, this proxy will read the host name and direct the client to the appropriate port based on that hostname.
It can easily be modified for your websites. See the comments in main.go.
NOTE:
This program runs on port 8080 for http connections and port 8443 for https.
This is so you won't need to run it with administrator priviliges. To make this
program work properly you should use the following command (for linux) to
redirect traffic from port 80 and 443 respectively:
sudo iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 8443
sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
When starting the server, tell goprox where your private key and fullchain
files are by specifying the fullchain and privkey, the ports you forwarded
to port 80 and 443, and the location the prox.config, as environment variables
at runtime:
prox80=8080 prox443=8443 proxConf=prox.config privkey=~/tlsCerts/privkey.pem fullchain=~/tlsCerts/fullchain.pem prox
