 There are two aspects to securing a web application(or context) within the Jetty server:

 In the above example, only users with an `admin` role will be able to perform `DELETE` or `POST` methods.
+
+===== Configuring Authorization with Context XML Files
+
+While the examples above show configuration of Authorization in a `web.xml` file, they can also be configured as part of the link#link:#deployable-descriptor-file[context xml file] for a web application.
+This is especially helpful if authorization needs change over time and need updated without re-packaging the whole web app.
+
+To do this, we add a section for security constraints into the context xml file for our web app as part of the `securityHandler`.
+In the example below, a `HashLoginService` is defined with authorization being granted too `foo/*` paths to users with the `admin` and `manager` roles.

+If roles changed in the future, administrators could easily change this context xml file without having to edit the contents of the web app at all.

+
+In addition to the distribution, security can be defined as part of an embedded implementation as well.
+Below is an example which, like the one above, sets up a server with a `HashLoginService` and adds security constraints to restrict access based on roles.
