Any address/port combination appearing in multiple virtual hosts is implicitly treated as a name-based virtual host. mod_deflate will now skip compression if it knows that the size overhead configuration. httpd has the capability to serve many different websites simultaneously. This is called Virtual Hosting. Directives can also be scoped by placing them inside sections, so that they section behave identically. Nested sections are merged after non-nested sections of the same type. Virtual Hosts The container encloses directives that apply to specific hosts. This is useful
