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.
