Reverse Proxy

gpu.st proxies all traffic to https://your-instance.mygpu.ws to your GPU instance on the configured port (80, by default). We handle certificate issuance, TLS termination, and by default, authentication.

Configuring the port

By default, all HTTP traffic is proxied to the standard HTTP port, 80. You can change this at any time with the share port command: share port my-instance 1234. This doesn't affect other settings like public/private visibility or the list of people the instance is shared with.

Public and private instances

By default, only users with whom the instance is shared can access the HTTP proxy. When they access https://your-instance.mygpu.ws, they'll be redirected to the gpu.st site so they can confirm their information and log-in.

You can make your instance public at any time with the share set-public command and take it private again with the share set-private command.

Headers

The gpu.st reverse proxy sends the following headers to your instance:

• X-Forwarded-For: a comma-separated list containing the previous value of the header (if any), plus the remote IP as known by gpu.st.
• X-Forwarded-Proto: https if the connection was over TLS; http if not.
• X-Forwarded-Host: the original Host header value.
