I'm using Apache 2.4.18 and OpenSSL 1.0.1e. According with https://mozilla.github.io/server-side-tls/ssl-config-generator/

Into sugested configuration I received it, but I don't know how to configure it on Windows because I'm not sure about param SSLStaplingCache, is it a directory?

# OCSP Stapling, only in httpd 2.3.3 and later
SSLUseStapling          on
SSLStaplingResponderTimeout 5
SSLStaplingReturnResponderErrors off
SSLStaplingCache        shmcb:/var/run/ocsp(128000)


  • Yes, when using the "shmcb" cache for UseStaplingCache, that is a file. Apache uses that file to naming a shared memory segment, which is shared among threads/processes. You simply need to make sure that the folders for that file exist.
