When I read tutorial on how to create /add virtual hosts, the last sentence is always something like:
... now restart apache and you are done!
Now, many (most|all) web hosts have a panel that allow you to create new virtual hosts which are activated almost instantly... and I am sure they didn't restart apache (inconveniencing hundreds of other users) just for my pleasure!
So how to change apache settings / adding virtual hosts, etc. and reloading the new settings without actually restarting the apache server?
