= File server example with directory listing

To try this example, you need GNU `make` and `git` in your PATH.

To build and run the example, use the following command:

[source,bash]
$ make run

Then point your browser to http://localhost:8080
to browse the contents of the `priv` directory.

Interesting examples include:

* http://localhost:8080/test.txt[Plain text file]
* http://localhost:8080/video.html[HTML5 video demo]

== HTTP/1.1 example output

[source,bash]
----
$ curl -i http://localhost:8080/test.txt
