[Radiant] Need to prevent stylesheets from caching

[Wes Gamble]

I need to allow a Radiant user to edit stylesheets and immediately see 
the results in generated pages, which means I want to effectively turn 
off caching for stylesheets.

I have set the cache timeout to 1 second in environment.rb (for some 
reason, setting it to 0 doesn't work in Chrome - great ;]), like so:

config.after_initialize do
  SiteController.cache_timeout = 1.second
end

and regular pages show this response header

  1.
     Cache-Control:
     max-age=1, public


But for a stylesheet request, I keep seeing a response header of

  1.
     Cache-Control:
     max-age=2592000, public


which is effectively 30 days.

Stylesheets are served through the SiteController like anything else - 
so I don't understand why they don't appear to be subject to the same 
caching controls as everything else?

Should stylesheets obey the normal page caching rules?

(I have also tried overriding the "cache?" method of StylesheetPage to 
no avail, FYI).

Thanks,
Wes
