You can research how to do something similar using whatever language you have on the backend.You can also do this through a grunt/gulp build step, if you have that at your disposal.There were lots of great comments on the CSS Caching article.I learned a lot from those comments, so I wanted to clear up some of the misunderstanding and highlight some of the great tricks other folks shared. Read the latest version of this article and head over to the new home of Chrome Dev Tools for the latest tutorials, docs and updates.This tutorial covers editing CSS styles using various Dev Tools aids.
You might be aware of the j Query method, which allows you to select an element if it has any of another selector as a descendant. But if you know a little something about the HTML structure, you can use a combination of positional selectors to mimic it. Recently, I was working on a dropdown navigation bar and wanted to differentiate the menu items which contained sub menus from those that didn't.
Press F5 or refresh the page or click on a navigation link on page. Read this as "304 means that everything you know is good; everything else you get in this response can be ignored" Further information: The spec ( says that the response SHOULD NOT include other entity headers (or even MUST NOT under some circumstances).
Hard refresh page and page displays correctly again. There are apparently a lot of servers that send gibberish such as Content-Type:text/plain in their 304 for CSS resources, can't we just handle the 304 and ignore the rest? Hmm, so it seems many web servers are serving up 304 HTTP responses with actual contents that we're expected to serve I would actually read it differently: Many web servers are serving up 304 HTTP responses with actual content that you are *NOT* expected to serve (but which is generated by the server somewhere along the line anyway, such as a default Content-type and stuff) I therefor agree with Ken: Handle the 304, and ignore the rest.
Extension developers should be careful about updating extensions that have a dependency on the native binary (for example, legacy extensions using NPAPI).
Every few hours, the browser checks whether any installed extensions or apps have an update URL.
Easiest way I've found is in Chrome Dev Tools settings.
