Commit Message

Bust proxy_pass DNS cache; restore proxy 'Host:'

Two problems arose with https://tock.18f.gov/ last night.

Problem the first, the original IP address for https://tock-app.18f.gov/
expired. nginx actually caches DNS responses for `proxy_pass` hosts when
they're hardcoded. The workaround: force it to be a variable, per:

  https://www.jethrocarr.com/2013/11/02/nginx-reverse-proxies-and-dns-resolution/

Problem the second, somehow the Cloud Foundry route for tock.18f.gov
disappeared. Once the DNS issues was (initially) resolved by restarting nginx,
https://tock.18f.gov/ started returning:

  `404 Not Found: Requested route ('tock.18f.gov') does not exist.`

Removing the `proxy_set_header Host $host` directive, originally added in
18F/hub#359, caused https://tock.18f.gov/ to work again, sort of. After
@batemapf made administrative changes, he was bounced back out to
https://tock-app.18f.gov/ instead.

After discussion with @jmcarp, @dlapiduz, and @GUI, we figured out the
cache-busting solution to the stale IP issue, and that restoring the
tock.18f.gov mapping in Cloud Foundry enabled us to restore the
`proxy_set_header` directive.
