Cache-Control and Last-Modified and ETag, oh my! @ Kansas City Developer Conference

Cache-Control and Last-Modified and ETag, oh my! @ Kansas City Developer Conference

Ever wonder exactly what combination of Cache-Control, Last-Modified, Expires, ETag, Vary, and Pragma headers will keep your content cached by browsers just long enough? And what exactly is a HTTP 304 anyway?

In this talk, we’ll take a look around at the available HTTP caching headers, what their values mean, and how browsers and proxies react. We’ll cover the best practices on client cache invalidation, the benefits of sending a Not Modified response, and briefly talk about the changes in HTTP 2.0 (SPDY) around caching.
