apache代理出现这个错误
解决：No protocol handler was valid for the URL /img. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.
用apache配置虚拟主机做代理出现这个错误知道是为什么嘛，是少加了几个module靠
要用apache配置虚拟主机需要加载这几个module
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_http_module modules/mod_proxy_http.so
