@jcarizza instead of adding a new setting, I would add a new template tag admin_interface_static which wraps the static template tag and that automatically adds the nocache parameter only if the url starts with STATIC_URL settings (simple yet effective and zero configuration needed).

I'm sorry that you worked in another direction, I would suggest you to discuss the solution in the issue before working on a PR the next time, anyway... thank you very much for this PR!

Hi @fabiocaccamo

Sorry I sent the PR before a previous discussion, I needed to fix that ASAP in my application.

I think this solution would be less intrusive and simpliest.

The new template tag will check if the files are the default django storage or if they start with STATIC_URL and add or remove the nocache tag.
