Path to a directory with CA revocation certificates]
server config, <Global>, <VirtualHost>
1.2.7rc1 and later
The TLSCARevocationPath directive sets the directory for the Certificate Revocation Lists (CRL) of Certification Authorities (CAs) for your clients. These are used during the verification of client certificates, if presented. This directive may be used in addition to, or as alternative for, TLSCARevocationFile.
The files in the configured directory have to be PEM-encoded, and are accessed through hash filenames. This means one cannot simply place the CRLs there: one also has to create symbolic links named hash-value.N. The c_rehash utility that comes with OpenSSL can be used to create the necessary symlinks.
