I have an application running on my development machine using Aptana & Webrick.
If I turn on caching (action_caching, written to tmp/cache), it works fine, but when I deploy the application to the testserver (running thin instead of webrick) the caching does not work...i.e. there are no files written to tmp/cache.
as far as I can tell, the webserver is the only difference here (even running the development-environment on the test server.
any clues?
