Yet another recipe to serve static media in Django: http://www.peterbe.com/plog/serve-your-static-stuff-in-django-with-nginx

We went with versioning the path and updating it based on the revision number in a Subversion repository. There's different ways to do it, but this is automatic and working well for us http://www.redrobotstudios.com/blog/2008/12/18/versioned-media-and-expires-headers-in-django/

Nice to hear that!

Tried it on the development version of KSM site (though with url prefix, not domain prefix). Works like a charm – most pages now require just a single request to fetch HTML, everything else is cached.

Editing URLs by hand is tedious and can be forgotten (especially when one image is used in many places). Passing it to VCS hook requires writing some more or less sophisticated script and that’s as good as writing patch for Less (CSS preprocessor) to do that. And yes, my solution would force downloading every component after one change. I don’t say your hints are bad or my solution is better, it just happens that I have different priorities.

I am just patching URLs manually when appropriate (linking to
/some/thing-13.png or /other/style-21.css and using nginx rewrite rule to strip -(\d ) from static files), and don’t find it too troublesome, but I guess it depends on the application.

Your idea is interesting, but I find one drawback. When does this number in domain name change? If it is common for all files, then even resources which were not changed would need to be redownloaded. If it is different for every image/file, then there are no chances for keepalive connection, and the browser may hog your server as the limit of 2 connections to one address does not apply.

PS There always is a possibility to patch the urls using version control hooks or build script hooks….

@lbadura: No, not yet. I’ll be trying that in some time for my brand new application I’m developing as my Honours Project.

It’s an interesting idea. Have you tried implementing it in one of your
applications ?

I was thinking about Google App Engine (again!). GAE gives you wildcard subdomains for free and AFAIK doesn’t allow synlinks. But for dedicated servers versioned path might be better.

Might be easier to just version a path.

eg : /static-1234/style.css, /static-1234/image.png
and then reference the image as url(‘./image.png’) from the stylesheet. No need for wildcard domains (which are often inaccessible).

Great idea anyway. Might try to implement it.
