just over the last few years I’ve come to really appreciate the fundamentals of HTTP, what’s going on under the hood when I’m building web applications. There are two sides of this. The first is that HTTP is in one sense http://bluegraybox.com/blog/2014/08/29/its-simpler-than-you-think-its-more-complex-than-you-think/ a very simple protocol. It’s just little text messages going back and forth between your browser and the web server. Whether I’m using Node or Django or some huge WSDL-driven Java XML-Beans monstrosity, what it’s doing isn’t rocket science; it’s just taking care of a bunch of tedious, nit-picky bookkeeping that I don’t want to be bothered with. If I really wanted to, I could just type the messages myself (and we’ll get to that in cgi error a minute). The practical upside of that is that you can use really simple tools to debug big, hairy, complex web applications. A few years ago, I was working in one of those Big Web Services systems with WSDL files and auto-generated Java code and layers and layers of middleware. We’d get some kind of error at the front end, and it’d be really hard to tell which piece had broken. So I ended up writing a cgi error not bunch of really simple shell scripts to test the web services in isolation. I’d spackle together something using curl, grep, and sed that built up and picked apart the messages as text, without dragging in all that mess of Java code. The flip side is that HTTP is actually a richer protocol than I’d realized. There’s a lot I didn’t know about it until I started building RESTful web services and trying to understand the “right” way to do it. There’s all this stuff you can do with status codes and headers that I’d been re-implementing at the application level. To take a recent example, I’ve been working on a web service that talks to other web services. Someone would make a call to us, we’d call the back-end services, they’d time out or barf up some sort of error, and we’d pass back a 500 error to our client. They’d see it and email us asking what was wrong with our service. It’d be nice to let them know it’s not our fault and that they should pester the back-end systems people instead. We could send back a message body that says something like, “Back-end systems failure. Original error message follows,” but it turns out we can say that just by returning a different status code. Not only is there a 502 status code, which means that a
