I am using a controller to serve up CSS. I am having a problem with
browsers not caching the CSS and think it is related to the Cache-
Control header. I tried the following, but the browsers still will
not cache:
headers[‘Cache-Control’] = ‘public’
Any ideas?
Thanks,
Tom
2 questions:
- do you have caching disabled (sorry but tech support always has to
know if the computers plugged in).
- If in firefox you go to Tools/page_info what are the values of:
-Cache Source
-Expires
-Meta
Thanks so much for looking into this with me! I’m getting desperate.

Yes, and have a used all browsers with the same the results.
- If in firefox you go to Tools/page_info what are the values of:
All of the results are taken from looking at the information on the
css being linked on the page using the following link:
The following results are using the Rails default headers:
Cache Source: Disk cache
Expires: Not specified
Meta: [nothing]
Also, the response headers (according to the web developer plugin):

The following results are after I have switched the headers[‘Cache-
Control’] to ‘public’:
Cache Source: Disk cache
Expires: Not specified
Meta: [nothing]

I’m having the same problem. I’m working on an app and deploying to a
development server and I noticed recently that css background images are
being reloaded on every page request. At first I thought it was my
browser but then I checked the headers and I find that they’re not
allowing caching:
Server: nginx/0.5.26
Date: Sun, 24 Feb 2008 23:44:48 GMT
Content-Type: text/html; charset=utf-8

I’m not sure whether to change the Rails config or the Ngninx server
config? Which would be correct? I’m not sure where this header is being
set so I don’t know where to tackle the problem.
