+Cowboy Cookie
+=============
+
+To compile this example you need rebar in your PATH.
+
+Type the following command:
+```
+$ rebar get-deps compile
+```
+
+You can then start the Erlang node with the following command:
+```
+./start.sh
+```
+
+Then point your browser to the indicated URL. This example allows
+you to use any path you want to try to show that cookies are defined
+site-wide. Try it in your browser!
