How to "reload" just one vhost file

I have a questi开发者_JAVA技巧on about apache configuration. Please help me! My server run multi virtual hosts (multi domains). But, every time I edit a vhost file, I have to restart apache, and, server have to reload all configuration files. That is expensive. Is there any way to "restart" or "reload" just one vhost configuration file? I googled but haven't found the solution.

I'm not 100% sure, but I think the answer is "No". I've been looking for this for a while, too. Although, you say "restart apache", what command are you running? Are you using the apache restart or reload command? You should only have to use reload.
