Kubernetes NGINX Ingress Path Rewrite Issue (noVNC Context Path Problem)

I’m deploying an application using noVNC on a Kubernetes cluster. I am using NGINX Ingress to expose the application externally and handling user-specific pods via context paths.

The Issue
Each pod is accessed through a user-specific path appended to the domain, like http://example.com/podPath. The index.html page loads correctly when accessed.
However, when clicking on internal links such as vnc.html, the path reverts to http://example.com/vnc.html, losing the context path /podPath. I need the links to maintain the context path, so they should be accessed as http://example.com/podPath/vnc.html.

What I’ve Tried

NGINX Ingress Annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$2
nginx.ingress.kubernetes.io/x-forwarded-prefix: /podPath
nginx.ingress.kubernetes.io/add-base-url: true

Despite these settings, the internal links still lose the context path and fall back to the root (/) path.

NGINX Ingress Path Rewrite:

I tried rewriting the paths in the Ingress using rewrite-target, but the internal links do not retain the /podPath and revert to the base domain instead.
Question
Is there a recommended way to maintain the context path when using noVNC behind NGINX Ingress?
How can I ensure that internal links always retain the podPath prefix without having to modify the noVNC HTML files? Is there any Ingress annotation or another method to solve this?
