lws minimal http server deaddrop

This demonstrates how you can leverage the lws deaddrop plugin to make a secure, modern html5 file upload and sharing application.

The demo is protected by basic auth credentials defined in the file at ./ba-passwords - by default the credentials are user: user1, password: password; and user: user2, password: password again.

You can upload files and have them appear on a shared, downloadable list that is dynamically updated to all clients open on the page. Only the authenticated uploader is able to delete the files he uploaded.

Multiple simultaneous ongoing file uploads are supported.

build

To build this standalone, you must tell cmake where the lws source tree ./plugins directory can be found, since it relies on including the source of the raw-proxy plugin.

 $ cmake . -DLWS_PLUGINS_DIR=~/libwebsockets/plugins && make
