Support custom proxy path aliases to avoid exposing third-party hostnames in URL

[canstand]

🆒 Your use case

When first-party proxy mode is enabled, the proxy URL path includes the actual third-party hostname verbatim. For example:

• PostHog: /_scripts/p/us.i.posthog.com/e/?...
• Umami (self-hosted): /_scripts/p/analytics.internal.example.com/api/send?...
  This is particularly problematic for self-hosted services like Umami: the proxy path leaks the user's internal domain (analytics.internal.example.com) to the public, exposing private infrastructure details that should never appear in client-facing URLs.

Even for SaaS services, exposing the raw hostname:

• Makes requests detectable by ad-blockers that inspect URL patterns
• Reveals which third-party services a site uses to any network observer
• May conflict with corporate firewall policies blocking known tracking domains

🆕 The solution you'd like

Hi @harlan-zw, rather than offering a half-baked solution based on my limited knowledge and AI assistance, I’d prefer to leave the implementation details to your expertise. By the way, really appreciate your hard work.

Thanks for the suggestion. In next minor you can do this:

export default defineNuxtConfig({
  scripts: {
    proxy: {
      // auto-generate a short opaque alias per domain → /_scripts/p/a1b2c3d4/
      alias: true,
      // or map specific domains
      // alias: { 'us.i.posthog.com': 'ph', 'analytics.internal.example.com': 'a' },
    }
  }
})
