I'm using a plugin to swoop the public directory over to s3 when I deploy with cap. The problem is that rails doesn't create these cache files until they are requested for the first time, so they aren't around du...
I'd like to install a plugin but I'm afraid it's going to install a lot of unnecessary stuff. I'd like to look at whatever file rake takes it installation instructions from and remove anything unnecessary. I believe this is the Rakefile. But I'm not sure what happens when rake looks at the rakefile - does it execute the entire rakefile ...

I guess I would just n...
EDIT -- the solution I posted below probably applies to any server (Nginx/Apache/anything else), because this header is set in Rails itself.
