Simon Willison: How do you configure the Apache server you describe in What are the advantages of running Apache behind nginx as opposed to just Apache by itself?

To what extent is it still valid to assume that your web app users are stupid?
They’re not stupid, but they’re probably WAY less web literate than you might expect—unlike you, they haven’t spent their entire career learning how the web works. See the famous “What is a browser?” video the Google Chrome team released:[... 71 words]
