Understanding deploy url and base href - node.js

Question

I'm developing an Angular app which I need to deploy on path
https://examplePath/AppSection/myApp
There is a server which redirect http://examplePath/AppSection to http://localhost:8080.
So, what I thinked to do is to set, in my Angular.json, the base href property like this:
"serve": {
[..]
"options": {
"host": "0.0.0.0",
"port": 8080,
"browserTarget": "myApp:build",
"baseHref": "/myApp/"
},
[...]
Doing this the app was accessible but all the calls to runtime.js, polyfill.js, main.js, etc... doesn't work because the browser tryed to find these file on
http://examplePath/myApp
Then I read about the deployUrl property so I set the angular.json like that:
"architect": {
"build": {
"builder": "#angular-devkit/build-angular:browser",
"options": {"deployUrl": "https://examplePath/AppSection/",
[...]
"serve": {
[..]
"options": {
"host": "0.0.0.0",
"port": 8080,
"browserTarget": "myApp:build",
"baseHref": "/myApp/"
},
[...]
This configuration works but with several issues and the browser usually remove AppSection/ from the url (I don't know why).
Then I edited my baseHref property adding AppSection/ and the result is:
"deployUrl": "https://examplePath/AppSection/"
"baseHref": "/AppSection/myApp/"
This configuration works but the browser has some problems with sockjs-node:
WebSocket connection to 'wss://examplePath/sockjs-node/570/wwadpefk/websocket' failed: Error during WebSocket handshake: Unexpected response code: 404 GET
https://examplePath/sockjs-node/570/00lb5fwe/eventsource 404 (Not Found) VM3475 sockjs.bundle.js:1
GET https://examplePath/sockjs-node/570/kqry21k3/htmlfile?c=_jp.a5d54nx 404 (Not Found)
Refused to display 'https://examplePath/sockjs-node/570/kqry21k3/htmlfile?c=_jp.a5d54nx' in a frame because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'none'".
Honestly I do not understood what I should do to deploy on a specific path.
