[RESOLVED] Expires Headers for images in stylesheets

[ideaoforder]

Hello, I have expires headers enabled with the default settings in a Rails app. Everything is working as expected, except for images loaded from stylesheets (i.e. style.css > background: url(/images/something.png). These don't get expires headers and thus aren't getting cached.

Is there a setting I have to change to get add expires headers to these as well?

Thanks!

check the MIME type of ".png", it should be in "Expires By Type" configuration

I currently have:

image/*=A604800, text/css=A604800, application/x-javascript=A604800

which should cover pngs. All images embedded in the html have proper expires headers--it's just the ones in the stylesheet that seem to have a problem.

what is in the response header when you access the file directly? check from firebug.

If you access it again by hitting enter from browser address bar, not using refresh, will you get 304 response?

I wonder if the request was served by rails dynamically.

You can also try add "image/png=A604800" explicitly, it does not hurt anything.

Excellent call! The images in question were being served by Rails dynamically--in this case because of an overzealous rewrite rule. Thanks so much! I don't know that I would have caught that.
