Support caching in memory? about caddy-cache

[ahoeg]

Instead of cache to disk just mount tmpfs to that path?

I did it once, but after doing a simple benchmark, it didn't improve the performance a lot. It seems that the operating system keeps a lot of buffers in memory so when you read the same file it doesn't have to go to disk.

Creating a new storage shouldn't be that hard, there is an interface for it (https://github.com/nicolasazrak/caddy-cache/blob/master/storage/response_storage.go), but it has to be benchmarked to check it's working as expected and it performs as expected. PR are welcome 😄

Yep fair enough, I agree it should be benchmarked. I have never worked in go, so I don't see myself having time to work out how to submit a PR any time soon I'm afraid.

Recently, I revise this repo to be consistent with the caddy 2's structure and support in_memory. In my experiment, caching in memory is actually more efficient. Anyone is interested can see this (https://github.com/sillygod/cdp-cache#test-result).
