Move static content to oauth2-proxy-static to avoid name collisions (#2223)

[StefanLobbenmeierObjego]

Description

Renamed the static folder to oauth2-proxy-static, so that content hosted by underlying application on /static can still be accessed.

Motivation and Context

Jupyter hosts resources on /static
Closes #2223

How Has This Been Tested?

Tested locally against the configuration that I use in production. Basically like this:

Built it like this:

GOROOT=/opt/homebrew/opt/go/libexec #gosetup
GOPATH=/Users/lobbenst/go #gosetup
/opt/homebrew/opt/go/libexec/bin/go build -o /Users/lobbenst/Library/Caches/JetBrains/IntelliJIdea2023.3/tmp/GoLand/___1go_build_github_com_oauth2_proxy_oauth2_proxy_v7 github.com/oauth2-proxy/oauth2-proxy/v7 #gosetup

ran it like this:

OAUTH2_PROXY_CLIENT_SECRET=censored \
OAUTH2_PROXY_COOKIE_SECRET=censored \
/Users/lobbenst/Library/Caches/JetBrains/IntelliJIdea2023.3/tmp/GoLand/___1go_build_github_com_oauth2_proxy_oauth2_proxy_v7  \
"--upstream=http://localhost:8888/" \
"--banner=-" \
"--footer=-" \
"--custom-sign-in-logo=-" \
"--cookie-secure=true" \
"--cookie-expire=8h0m" \
"--cookie-refresh=60m" \
"--cookie-domain=censored.de" \
"--http-address=0.0.0.0:8080" \
"--proxy-prefix=/jupyter" \
"--redirect-url=https://censored.de/jupyter/callback" \
"--email-domain=censored.de" \
"--provider=oidc" \
"--client-id=123456" \
"--oidc-issuer-url=https://login.microsoftonline.com/987645/v2.0" 

And for my local testing I had to add some more settings:
"--tls-cert-file=mycert.crt"
"--tls-key-file=mycert.key" \

I disagree with this change and I think you're using --proxy-prefix wrong.

The intention of the proxy-prefix flag is to allow you to set a unique path so that there isn't any overlap. In your case, I suspect you want to set the prefix to /jupyter/oauth2, that is, assuming there's no path within Jupyter that relies on oauth2 being a sub path.

Hi @StefanLobbenmeierObjego,

could you please test if the --proxy-prefix=/jupyter/oauth2 suggested by @JoelSpeed solves your issue?

[StefanLobbenmeierObjego]

Hi - thanks for the feedback. I will try it out, waiting for permissions to add that redirect uri in azure, but I will let you know

[StefanLobbenmeierObjego]

That worked, thank you very much for the support ❤️ I will also let the other affected person know in the linked issue
