Session resumption (caching)

[maciek-szn]

I tried googling the answer, but no luck, so I'll try here.

I ran my host through SSL Test. The result was something like this:

Session resumption (caching): No (IDs assigned but not accepted)
Session resumption (tickets): Yes

I'm not sure, but it seems to me that the answer in the first position should also be "Yes".

1. What does this even mean?
2. Is this an OLS configuration issue or some known OLS bug? My OLS configuration for Session Cache includes default settings (at the server and listener level), so it should be enabled.
3. Is this even a problem?

I host another site of mine on a commercial LiteSpeed server, and the answer for that one is "Yes".

Please navigate to SSL Listener > SSL, enable the Session Cache option, and see if that improves the situation.
However, keep in mind that most modern browsers use session tickets instead, so enabling the session cache may have limited impact.
