Management of content without clear cache

Question

How can I be sure that my user is using/seeing the latest version of my static content (js scripts, gifs, svgs, etc...) without telling them to clear their cache?

Answer 1

You have two broad options.

1. Disable caching altogether. That is a reasonable idea for dynamic content but generally poor for static content. So we will ignore this for now.
2. Generate different URLs / querystring for when your static content changes.

There are many possible approaches for option 2, for example:

• How to version javascript files in a Bundle?
• What is the best way to version javascript files in a huge asp.net legacy project
• Autoversioning CSS/JS in ASP.NET MVC?

Additionally, https://github.com/mwrock/RequestReduce is an option I have used in the past that you may want to have a go with.
