Re: Wildcard routes, subdomains and failing smoke-test

Shannon Coen

Hello Johannes,

You have observed expected behavior. Wildcard routes are designed to catch
all subdomains, unless other routes (wildcard or otherwise) exist to match.

Primary use cases for wildcard routes include custom 404 pages and
maintenance pages. If you've created a route based on the domain, then * can be used to provide a custom page for requests to
any subdomain.

Imagine if the wildcard only matched on the same subdomain level. To
accomplish the same goal, a user might need 125 wildcard routes (*,
*.*, *.*.*, etc).

Hi Dieu,
I had the same plans. But the solution feels a bit like a workaround. Is
this behaviour expected? If not should I try to fix it?

You might consider making a tiny custom 404 app and then map *
and * and any other sub domains to it so that it doesn't fall
through to your landing page app.
Would that work for you?

we got the following problem and I would like to know, if you have an
idea how to solve it.

We setup a view domains:
- <> is used for all the end user related things like
the landing page, documentation, etc. is used for internal
service endpoints and is used for all stuff related to CF
(api, uaa, login…) and some shared things like monitoring UI etc.

I created a route * to move all typos etc. of our customer touch
points to the central landing page. I was expecting <random>
will be still return an 404 Route not found. Now smoketests (using are failing, because the wildcard domain is working recursive
for all subdomains and is returning the content of *.bar app. (See:

* -> landing-page-app
* -> landing-page-app (why?)
* -> landing-page-app (why?)

So my question, were should we fix it? Should the gorouter not be
recursive over subdomains? Should we change the smoketest? Or am I on the
wrong track and we should do something else?
