+To expose files without a prefix, use `emptyInput`. For example, using the [netty](../server/netty.md) interpreter, the

 A single file can be exposed using `fileGetServerEndpoint`.
 
 The file server endpoints can be secured using `ServerLogic.prependSecurity`, see [server logic](../server/logic.md)
