mountWelcomePageAction Action

Reply with the built in Fluxzy welcome page so users can confirm their device is routing through the proxy before they trust the CA.

The welcome page is the cheapest way to answer the question every new proxy user asks first: "is my device actually going through Fluxzy?". A short, recognisable HTML reply on a reserved hostname removes that uncertainty in a single browse and frees you to focus on the actual captures.

When to use this action

Reach for mountWelcomePageAction when you want a deterministic, friendly response that proves the client is actually going through Fluxzy. It removes any ambiguity from the first browse a tester does after configuring proxy settings.

Good fits:

  • The first hop in a mobile onboarding playbook, before the user installs the root CA.
  • A health check served on a memorable hostname like fluxzy.local or proxy.test.
  • A demonstration during pair debugging sessions to show what the proxy can do.

This action takes no settings, so combine it with a hostFilter or a path based rule to control exactly when the welcome page appears.

Real world examples

Show the welcome page on a dedicated hostname

Reserve a memorable hostname that a tester can type from any browser to confirm the proxy is intercepting traffic.

Serve the welcome page only on a specific path

Useful when you share the proxy with other tooling. The welcome page only triggers when someone hits the exact onboarding URL.

Frequently asked questions

Can I customise the welcome page content?

Not through this action. If you need a branded page, host static files locally and use serveDirectoryAction or return your own payload with mockedResponseAction.

Does the welcome page require the CA to be trusted?

Only if you reach it over HTTPS. On plain HTTP the action works immediately, which is why it pairs well with mountCertificateAuthorityAction during first time setup.

Is it safe to keep this rule enabled all the time?

It is harmless but noisy. Scope it to a hostname or path you control so it does not interfere with real captures.
