I got this idea from kernel only... if you compile any part of kernel as module, then you can insert, remove or modify it and then re-insert the kernel-module without restarting machine atall :-) and Its not that memory expensive in case of kernel... But as we are now talking about user-space process, things do change I am not sure, but I think that it should be possible to do the same with userspace processes also > > * Adding the sorts of features you suggest would substantially bloat > httpd; there's a reason why you must have a GB to run a windows box > anymore as a workstation :) httpd's optimization is one core mission, > the fastest possible service of individual requests.

Thanx, I will surely go through them to see how it is done currently. -- Regards, Pravin Shinde --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
