Never heard about G-wan before, but from a quick read-through it is not quiet standard. It seems like somewhat unusual design, but interesting. From the g-wan website: G-WAN is an all-in-one solution because communicating with other servers (FastCGI, SCGI, etc.) takes time (enlarging latency), and wastes CPU and RAM resources when the network can be avoided. Also, supporting many programming languages lets G-WAN serve most needs instead of having to use slower backend servers and fontend caches. Remember that our goal here is to use the ultimate low-latency and resource-saving solution. This is why G-WAN is a: -Web server -App. server -Cache server -Key-Value store server -Reverse-proxy and elastic load-balancer server
