Steps to Reproduce

Deployment of two code-servers，using sub-path access
eg: http://xxxx:8082/v2/ , http://xxxx:8082/v3/

1. k3d cluster create dev-cluster --port 8082:80@loadbalancer --servers 1 --agents 2 --k3s-arg "--disable=traefik@server:*"
2. helm install traefik traefik/traefik -f values.yaml
3. kubectl apply -f code-server-v2.yaml
4. kubectl apply -f code-server-v3.yaml

Expected

Visit http://xxxx:8082/v2/ and http://xxxx:8082/v3/ do not interfere with each other

Actual

Creating a page and accessing it in code-server-v3, refreshing the page in code-server-v2 can actually access it, and it will prompt that there is no file

Logs

No response

Does this issue happen in VS Code?

• I cannot reproduce this in VS Code.

Are you accessing code-server over HTTPS?

• I am using HTTPS.

Notes

I am using HTTP

@code-asher will this be fixed in the next version with you db state work?

[code-asher]

Yeah, looks like the same issue!

[jsjoeio]

@heroyanglonghui can you try using 4.1.0 and seeing if the same issue exists?

[heroyanglonghui]

ok. I tried to test it with version 4.1.0 and the problem is fixed, thanks! @jsjoeio @code-asher 🎉🎉
