Re: [ECS] Web server "events" needed ? Mark Gilmore Thu, 10 Feb 2000 10:53:52 -0500

Well, - I'm not really sure (if it makes better sense) :-).
ECS can generate it's own web pages withOUT also acting as
a server (you would set ECS_HTM_GEN, but NOT ECS_WEB_SERVER).
If you set ECS_HTM_GEN to {d} (e.g. 30), ECS would generate
updated pages every {d} seconds. But unless ECS is acting
as a server, you would have no way of SETTING States.
Your serve :-)
