+# MDEV-16266 Reload SSL certificate
+# This test reloads server SSL certs FLUSH SSL, and checks that 
+# 1. old SSL connections (that existed before FLUSH) still work and use old certificate
+# 2. new SSL connection use new certificate
+# 3. if FLUSH SSL runs into error, SSL is still functioning
+# SWtatus variable Ssl_server_not_after is used to tell the old certificate from new.
