i host diablo_web_simple on my root running nginx when i use chrome it only loads the chunks of diabdat.mpq once -> then loads them from cache when using firefox it always loads the chunks and doesnt use cache -> this results in slower load and less performance

diabdat.mpq = ~270mb chunksize = between 1-7mb combined chunksize of loading game: ~65mb

i already set in about:config browser.cache.check_doc_frequency 2

i also set headers for caching this file in nginx

nothing works pls help

I don't have any experience with serving files based on ranges (HTTP Status code 206)...

First question: is Firefox caching the chunks?

After the first load, if you open about:cache and click into the disk cache, can you Ctrl+F Find those chunks listed there?

If so, Second question: why doesn't Firefox match up the new requests to the cached chunks?

Maybe a case of RCWN (Race Cache With Network), see about:networking#rcwn

  • about:config => network.http.rcwn

jscher2000 -> no it does not cache the chunks -> nothing in about:cache disk

cor-el -> i dont know what to look for in RCWN

here a picture of WebConsole of one of the first partial chunks of diabdat.mpq
