I have already tried some "tricks" related to KeepAlive settings, without luck. Here is my current configuration, any suggestions? #keepalive Off ## I have tried this, does not help #SetEnv force-proxy-request-1.0 1 ## I have tried this, does not help #SetEnv proxy-nokeepalive 1 ## I have tried this, does not help #SetEnv proxy-initial-not-pooled 1 ## I have tried this, does not help KeepAlive 20 ## I have tried this, does not help KeepAliveTimeout 600 ## I have tried this, does not help ProxyTimeout 600 ## I have tried this, does not help NameVirtualHost *:80

It does not provide any caching abilities. If you want https://www.apachelounge.com/viewtopic.php?p=8241 to set up a caching proxy, you might want to use the additional service of the mod_cache module. Thus, in order to get the ability error reading of handling HTTP proxy requests, mod_proxy and mod_proxy_http have to be present in the server.

Environment variables below that don't specify specific values are enabled when set to any value. proxy-sendextracrlf Causes proxy to send an extra CR-LF newline on the end of a request. This is a workaround for a bug in some browsers. force-proxy-request-1.0 Forces the proxy to send requests to the backend as HTTP/1.0 and disables HTTP/1.1 features. proxy-nokeepalive Forces the proxy to close the backend connection after each request. proxy-chain-auth If the proxy requires authentication, it will read and consume the proxy authentication credentials sent by the client. With proxy-chain-auth it will also forward the credentials to the next proxy in the chain. This may be necessary if you have a chain of pro
