Exactly, but for a public-facing web site we have no saying in whether clients use a firewall or not :(
Also, doesn't this mean that someone could effectively take down the entire server by opening (MaxWorkers) requests every 5 minutes and then just not respond to / read the response at all? Wouldn't this make apache a very easy (D)-DoS target? Has anyone else experienced this issue? Is there a way to reduce the write-to-client timeout in Apache? FWIW, I think I'll look into PHP's built-in outbut buffering feature to reduce the the issue of locked PHP session files while writes time out. - Frode On Thu, Nov 23, 2006 at 11:12:52 +0100, Roman Fiedler wrote: > Hi, > > seems to be just a firewalling/networking problem.
