Pagespeed seems to be working well and making sites load faster, however I can't seem to clear the cache which makes development very difficult. I have used the clear cache feature under webserver configuration, but I still see the old CSS. If I turn pagespeed off and switch to lighttpd and back to apache it shows the current CSS. The very strange thing is that if I turn it back on, I see the old CSS again and I have completely deleted the var/cache/mod_pagespeed directory and still get the old CSS. I have cleared the browser cache and even checked on other computers.
Any idea what's going on?
