ng serve not working behind reverse proxy basehref/servepath

首先，通过转发的 /proxy/4200/ URL 复现报告中的 ng serve --host 0.0.0.0 --disable-host-check 配置。调查 basehref 和 servepath 选项如何影响 Angular node-resource URLs 和重定向，包括 /proxy/4200/ 重复的情况。当转发的开发服务器能够在路径不错误的情况下加载这些资源时，即视为完成。

Command

serve

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

before vite

Description

I provide remote training for Angular using VSCode in the browser.
It is no longer possible to use the vscode port forwarding to access the ng dev server as basehref and servepath combinations to not yield the correct result when @angular node resources are to be loaded. It works for all other assets/files in the project.

Minimal Reproduction

Use code-server oder vscode server access through web browser.

ng new
ng serve --host 0.0.0.0 --disable-host-check

Open the forwarded port, URL becomes f.e.
https://student01.remote-training.de/proxy/4200/

Anything else relevant?

I tried various configuration combinations using prebundle, basehref and servepath only to experience worse problems like beeing redirected to https://student01.remote-training.de/proxy/4200/proxy/4200/
