Caddy loves Iris

The Caddyfile shows how you can use caddy to listen on ports 80 & 443 and sit in front of iris webserver(s) that serving on a different port (9091 and 9092 in this case; see Caddyfile).

Running our two web servers

1. Go to $GOPATH/src/github.com/kataras/iris/_examples/tutorial/caddy/server1
2. Open a terminal window and execute go run main.go
3. Go to $GOPATH/src/github.com/kataras/iris/_examples/tutorial/caddy/server2
4. Open a new terminal window and execute go run main.go

Caddy installation

1. Download caddy: https://caddyserver.com/download
2. Extract its contents where the Caddyfile is located, the $GOPATH/src/github.com/kataras/iris/_examples/tutorial/caddy in this case
3. Open, read and modify the Caddyfile to see by yourself how easy it is to configure the servers
4. Run caddy directly or open a terminal window and execute caddy
5. Go to https://example.com and https://api.example.com/user/42

Notes

Iris has the app.Run(iris.AutoTLS(":443", "example.com", "mail@example.com")) which does the exactly same thing but caddy is a great tool that helps you when you run multiple web servers from one host machine, i.e iris, apache, tomcat.
