go-reverse-proxy

To build and run the project:

go build
./go-reverse-proxy

I also included a small go program which starts two backend servers (from a corresponding config file):

cd backend_servers/
go build start_backend.go
./start_backend

Here is a list of curl commands for testing the reverse proxy:

1. Valid token request:

curl -H "X-Auth-Token: valid-token-1" http://localhost:8080/some/path

2. Invalid token request:

curl -H "X-Auth-Token: invalid-token" http://localhost:8080/some/path

3. No token:

curl http://localhost:8080/some/path

4. Websocket request with a valid token:

websocat -H="X-Auth-Token: valid-token-1" ws://localhost:8080/ws

5. Websocket request with an invalid token:

websocat -H="X-Auth-Token: invalid-token" ws://localhost:8080/ws

6. Websocket request with no token:

websocat ws://localhost:8080/ws
