+`JasperserverRestClient` supports three authentication types: REST, SPRING and BASIC. 
+`REST` type of authentication means that your credentials are sent through `/rest/login`, and in the `SPRING` mode – through `/j_security_check directly/`. Using these types you obtain JSESSIONID cookie of authenticated session after sending credentials.
+In the `BASIC` mode `JasperserverRestClient` uses basic authentication (sends encrypted credentials with each request).
+Client uses `REST` authentication by default but you can change the mode using follow code:
+```java
+config.setAuthenticationType(AuthenticationType.SPRING);
+```
+Or specify authentication type in RestClientConfiguration instance (for details, read section [Configuration](https://github.com/Jaspersoft/jrs-rest-java-client/blob/master/README.md#configuration).
+Please notice, the basic authentication is not stateless and it is valid till method logout() is called or the application is restarted.

+It is possible to log outgoing requests and incoming responses using `logHttp` property of `RestCleintConfiguration`:
+```java

 ###Possible issues
 1. <strong>Deploying jrs-rest-client within web app to any Appplication Server, e.g. JBoss, Glassfish, WebSphere etc.</strong>
 jrs-rest-client uses the implementation of JAX-RS API of version 2.0 and if your application server does not support this version you will get an error. To solve this problem you need to add to your application a deployment configuration specific for your AS where you need to exclude modules with old JAX-RS API version. Example of such descriptor for JBoss AS you can find below:
