[Geocoding] Nominatim API and HTTPS

[Sarah Hoffmann]

Hi all,

at openstreetmap.org we plan to make HTTPS mandatory in the near
future on all our servers. That means that all HTTP urls will then
automatically redirect to HTTPS. This also affects the API at
nominatim.openstreetmap.org and the data updates at
planet.openstreetmap.org.


If you are a user of the API or even a library developer, please
take a minute to update all nominatim urls in your code to HTTPS.
This will avoid unpleasant surprises in case your client does not
support redirects.


If you run a Nominatim installation that regularly updates
from planet.openstreetmap.org, please switch the update URL to HTTPS.

This is particularly important for users of Nominatim 2.x.
You *must* switch the baseUrl in settings/configuration.txt or
updates will stop working once we put the redirect in place.

Users of Nominatim 3.x need to adapt CONST_Replication_Url in
settings/local.php.

Kind regards

Sarah
