Resin caching breaks Confluence stylesheets
Resin 2 has a broken caching algorithm that for certain URLs will always return a 304 Not-Modified status and return no content, even when the client does not send a Last-Modified header. This usually results in broken stylesheets in Confluence.
To fix this disable caching in Resin by commenting out the following line in resin.conf:
<!-- <cache dir='cache' size='4096' entries='4096'/> -->
