Apache Proxy: No protocol handler was valid
I am trying to proxy a subdirectory to another server. My httpd.conf: RewriteEngine On ProxyPreserveHost On RewriteRule .*subdir/ https://anotherserver/subdir/ [P] The problem is that Apache is always logging this: AH01144: No protocol handler was valid for the URL /subdir/. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule., referer: http://localhost/ So after searching the internet, I have activated these modules: LoadModule headers_module modules/mod_headers.so LoadModule proxy_module modules/mod_proxy.so
