Benchmarking a site behind login & SSL

Does anybody know of a way to benchmark a site with something like RailsAnalyzer's Crawler tool on a site where 99% of the business is conducted behind a login, and 100% is SSL encrypted? Crawler doesn't seem to handle either. I suppose we could hack the login to 'simulate' logging in and setup the test server without SSL, but I'd rather test **everything** not just the parts that are convienent.
