Current users

[centauratlas]

I was curious if anyone is using PHP to access part of Apache (2.0.x specifically) to generate information like:
"current active users: xxx"?

I have seen those before on sites that don't require log-in or cookies so I think that there must be some method of doing so.

What I was thinking was that since Apache obviosuly knows that there are "n active client requests" (e.g. related to the MinSpareServers directive) that there must be someway to access that information.

Anyone doing this?

Those sites are typically tracking users by their IP instead of a user name. It is not an apache trick.

I've seen it on WebStar too (perhaps by IP there, but I don't know). Anyway, is there a way to use PHP to pull out the current number of "active" Apache processes?
