AMuleWeb
From AMule Project FAQ
AMuleWeb is an utility that listens for HTTP connections at port 4711 (by default, although ti can be changed through Preferences) and allows remote users to control aMule using just a web browser.
aMule itself doesn't support listening to HTTP connections, so the external utility AMuleWeb is used. This utility listens for remote connections, and once the link between AmuleWeb and the remote user is established, it connects to the aMule main program using the External Connections mechanism.
