-Connection timeout to the OCSP responder in seconds
+Connection timeout to the OCSP responder in seconds.
+On POSIX systems, when running as an OCSP responder, this option also limits
+the time that the responder is willing to wait for the client request.
+This time is measured from the time the responder accepts the connection until
+the complete request is received.
+
+=item B<-multi process-count>
+
+Run the specified number of OCSP responder child processes, with the parent
+process respawning child processes as needed.
+Child processes will detect changes in the CA index file and automatically
+reload it.
+When running as a responder B<-timeout> option is recommended to limit the time
+each child is willing to wait for the client's OCSP response.
+This option is available on POSIX systems (that support the fork() and other
+required unix system-calls).
=item B<-CAfile file>, B<-CApath pathname>
The private key to sign OCSP responses with: if not present the file
specified in the B<rsigner> option is used.
+=item B<-rsigopt nm:v>
+
+Pass options to the signature algorithm when signing OCSP responses.
+Names and values of these options are algorithm-specific.
+
=item B<-port portnum>
Port to listen for OCSP requests on. The port may also be specified
