I've been using firebug and it seems to be setting the cache headers correctly (firefox doesn't re-download static files each time). I guess it's just a problem I have to deal with. I think you're right about the load-tester not using headers, so maybe it won't be as big a problem as I thought.
One more thing though.. In the appengine dashboard the static requests claim to be consuming 0kb, even when I clear my browser's cache. Yet these requests seem to be counting against the quota.. Does it just report it incorrectly? Thanks again.. On Feb 18, 5:49 pm, Locke <[email protected]> wrote: > Just use the "Live HTTP headers" Firefox add-on.
