Remember, in order to make the following examples work, you have to enable mod_proxy and mod_proxy_fcgi.

This application should be able to handle multiple concurrent connections. mod_proxy enables connection reuse by default, so after a request has been completed the connection will be held open by that httpd child process and won't be reused until that httpd process routes another request to the application. If the FastCGI application is unable to handle enough concurrent connections from httpd, requests can block waiting for the application to close an existing connection. One way to resolve this is to disable connection reuse on the ProxyPass directive, as shown in the following example:

The balanced gateway needs mod_proxy_balancer and at least one load balancer algorithm module, such as mod_lbmethod_byrequests, in addition to the proxy modules listed above. mod_lbmethod_byrequests is the default, and will be used for this example configuration.
