-
-You can enable the following middleware using the "middlewares" config parameter:
-
-- "firewall": Limit access to specific IP addresses
-- "cors": Support for CORS requests (enabled by default)
-- "xsrf": Block XSRF attacks using the 'Double Submit Cookie' method
-- "ajaxOnly": Restrict non-AJAX requests to prevent XSRF attacks

 ## TreeQL, a pragmatic GraphQL
 
 [TreeQL](https://treeql.org) allows you to create a "tree" of JSON objects based on your SQL database structure (relations) and your query.
 
 The GeoJSON functionality is enabled by default, but can be disabled using the "controllers" configuration.

 ### Authentication
 
 Currently there are three types of authentication supported. They all store the authenticated user in the `$_SESSION` super global.
