I’ve just installed rt3.6 and saw a lot of requests done by Firefox. Looking
a bit deeper at it I saw, that it was fetching all the .css, .js and images
all the time. Looking at the cache I saw, the ‘Expires’ date was set on
1970-… . So I changed my autohandler in NoAuth/css to
$r->header_out(‘Expires’, HTTP::time2str (time + 180 * 24*3600 ));
and in NoAuth/js accordingly and now Firefox renders the pages much faster !
Maybe this helps somebody else.
