Thanks Jonathan. Why did Google chose to build its own proprietary web server? Was there a specific requirement or need that Apache or other alternatives couldn't support? I suspect around that time the first event-based (async I/O /w connection multiplexing) web server was Zeus, which was commercial and likely not worth looking into it and soon thereafter there was Lighting HTTPD or whatever it's called. Did you want to, perhaps, implement your own similar design, optimised for your use cases, without having to say, pay, for Zeus?
