Does anyone know if while Apache HTTPD is doing a reload (which, let's say, takes five seconds) can it still serve requests during that time?

            As far as I know, no. However there is a graceful restart which stops child nodes halting mid-request which I think takes care of this.

              First of all, you say reload, but assuming you mean 'reload' OR 'restart':
   /my/path/to/httpd restart
Causes the current httpd process to exit, which means for a time the server appears to be down, as in not serving any requests.
/my/path/to/httpd reloadDoes not cause the current server to exit, which means connections are never refused and thus the server never looks down (but is rather slow for a little while)
- Will cause all long running httpd daemon requests to exit

              Hi. Thanks for your answer. Sorry, I didn't mean 'reload' or 'restart'. Just 'reload'. I understand that a 'restart' brings the whole server down. I was just wondering about the 'reload'.

                No worries, it's better to be clear about the difference between the two anyway. Hope that helped you.
