Servers are accessed by HTTPS protocol. Server fully qualified domain name varies on ISDS
instance and authenticiation method.

Two ISDS instances exist. Each instance has unique two-level domain name:

ISDS Instance           Base domain
---------------------------------------------
Production instance     mojedatovaschranka.cz
Testing instance        czebox.cz


Different log-in methods require different subdomains and URL path infixes:

Authentication method                   Subdomain   Path
---------------------------------------------------------------
HTTP basic                              ws1         /DS/
System certificate                      ws1c        /cert/DS/
Commercial certificate with HTTP basic  ws1c        /certds/DS/
System certificate and box ID           ws1c        /hspis/DS/
OTP without client certificate          www         /apps/DS/


For example, when logging into production instance with HTTP basic
authentication, the base URL is <https://ws1.mojedatovaschranka.cz/DS/>. When
logging into testing instance with OTP method, the base URL is
<https://www.czebox.cz/apps/DS/>.
