防止Corona缓存我的网络请求

Question

I couldn't find any information in the documentation that mentions resources caching, but from my tests it seems like Corona caches files which is not what I wanted.

-- if this file has been downloaded before, Corona will be happy to ignore it
-- for me
network.request(some_url, "GET", network_handler, {
    filename = some_file_name,
    baseDirectory = system.CachesDirectory
})

As a web developer, I am used to dealing with browsers' caching shenanigans. Applying the same fix seems to fix the issue:

network.request(string.format("%s?_=%d", some_url, os.time()), "GET", network_handler, {
    filename = some_file_name,
    baseDirectory = system.CachesDirectory
})

This is definitely not optimal but I couldn't find any useful information in the documentation. Caching also seems to only affect downloading files. Normal network requests are not affected.

Any ideas on how to disable caching properly?

Credit to ldurniart , it seems that adding

Cache-Control: no-cache

to the header forces the system to disregard the cache, though it ultimately depends on the system to decide.
