RDP alapu RemoteApp (https://technet.microsoft.com/en-us/library/cc755055(v=ws.11).aspx) + Myrtille (https://github.com/cedrozor/myrtille)
Myrtille provides a simple and fast access to remote desktops and applications through a web browser, without any plugin, extension or configuration.
Technically, Myrtille is an HTTP(S) to RDP gateway.
