Shannon,
What are your current thoughts on "maintaining routes with no backends in
the routing table" ? I quickly scanned the routing backlog few days ago
without yet finding trace of it.
I wish we could have used the opportunity of the cf summit "project office
hours" routing session [1] to have interactive exchanges around these use
cases. Unfortunately, my autosleep session [2] is scheduled at the exact
same timeslot.
If the cf foundation organizers were able to swap sessions that would be
great. I'll send a separate email to events(a)cloudfoundry.org, is there are
other community members suffering from the same conflict.
Thanks in advance,
Guillaume.

Here is another minor use case. My users are often confused that a
stopped app returns a 404 instead of a 503. So, we implement that
functionality for the user using an app mapped to wildcard routes that
constantly asks the CC for valid routes. This works for wildcard
domains but not one off domains.
It might be better if the router returned a 503. At least for routes
bound to apps. Not sure if this should extend to routes not bound to
apps.
+1 for that proposal. A 404 also causes issues when crawler remove pages
from their index. A 503 has less side effects. I would also prefer a 503
service unavailable when a route is not bound - because there is no service
for this route. IMHO the meaning is much closer to what has happended.

Hello Guillaume,
Thank you for sharing your thoughts on these use cases. I can see
how having
a route service field requests for an app, whether the app is up on
not,
could be useful.
However, enabling this would significantly change how routes are
registered
for apps on Cloud Foundry, and how the router handles the route
lookup.
Routes are not currently enabled in the routing tier unless they are
mapped
to an app, and only when the app is determined healthy.
You are proposing the router maintains routes which have no
backends, and
instead of a failed lookup determining whether a 404 is returned,
the router
should figure out whether a route has any backends or a route service.
I'll chew on your use case and keep my ear out for additional use
cases for
maintaining routes with no backends in the routing table.
Best,
Shannon
