For people who like 折腾
Note only "ssl_stapling_file" with single cert is supported. Use it as your own risk.

why you remove that feature from your repo?

@pleaz Because I don't use BoringSSL now.

You could get it on: https://raw.githubusercontent.com/kn007/patch/35f2b0decbc510f2c8adab9261e3d46ba1398e33/Enable_BoringSSL_OCSP.patch

Restore this patch and increase the allowed stapling file size(for some CA like GlobalSign 0b83bc2).

I wrote a article for auto-rebuild OCSP stapling file with shell and atd(at cron).
