Hi Brad,
Reviewing your messages and I just noticed that this question somehow got lost (I was on PTO back when you sent them, sorry for missing them).
Those values are used to configure the javax.net.ssl.SSLContext:
sslContext.getClientSessionContext().setSessionCacheSize(optionMap.get(Options.SSL_CLIENT_SESSION_CACHE_SIZE, 0));
sslContext.getClientSessionContext().setSessionTimeout(optionMap.get(Options.SSL_CLIENT_SESSION_TIMEOUT, 0));
sslContext.getServerSessionContext().setSessionCacheSize(optionMap.get(Options.SSL_SERVER_SESSION_CACHE_SIZE, 0));
sslContext.getServerSessionContext().setSessionTimeout(optionMap.get(Options.SSL_SERVER_SESSION_TIMEOUT, 0));
The default values for all of those is 0. It appears to me that client cache time in the IIS could be equivalent to SSL_CLIENT_CACHE_TIMEOUT.
Best regards,
Flavia
