apache 配置虚拟主机 url重写功能

<VirtualHost *:80>
        # The ServerName
directive sets the request scheme, hostname and port that
        # the server
uses to identify itself. This is used when creating
        # redirection
URLs. In the context of virtual hosts, the ServerName
        # specifies
what hostname must appear in the request's Host: header to
        # match this
virtual host. For the default virtual host (this file) this
        # value is not
decisive as it is used as a last resort host regardless.
        # However, you
must set it for any further virtual host explicitly.

disabled at a global level, it is possible to

line for only one particular virtual host. For example the

line enables the CGI configuration for this host only

been globally disabled with "a2disconf".
