I’d agree with Peter - start by breaking up the Minimee calls to give you lots of little minimee downloads: depending on how much stuff you have, maybe even try doing one per item to begin with. Once you have done this, you can exploit the
queue / display feature to stack up more than one entry to see how combinging them works. For example:
… css stuff …
… more css stuff …
… other stuff …
will give you a single block of minimsed CSS cached by minimee that combines the two ‘header’ queues entries.
