                 You should not expose a SpatiaLite-enabled Datasette instance to the public internet without taking extra measures to secure it against potentially harmful SQL queries. 
                 The following steps are recommended: 
                 
                     
                         Disable arbitrary SQL queries by untrusted users. See  Controlling the ability to execute arbitrary SQL  for ways to do this. The easiest is to start Datasette with the  datasette --setting default_allow_sql off  option. 
                     
                     
                         Define  Canned queries  with the SQL queries that use SpatiaLite functions that you want people to be able to execute.
