What was the first browser-based control panel software?

The type of software is ubiquitous nowadays: the "terminal" to get into some piece of hardware or software is the web browser, with a control panel.

I know of the Cobalt Qube, which is what inspired Dave Winer to change Frontier and morph it into what became Manila. He said that Cobalt was his inspiration.

The entire genre of content management system/weblogging software works through the web browser as a control panel.

Nowadays there are web servers hard wired into all sorts of equipment: Routers, an air station, printers--too many to say.

What I'm trying to figure out is -- who was the first? Was it Cobalt? Someone else? Do you know?

UPDATE: Bless those medical geek-men! Al helps get the question out, and Jason Levine at Q helps answer -- taking it back to Oracle WebServer 1.0, vintage 1995.
