18Disable curl's use of SSL session-ID caching. By default all transfers are
19done using the cache. Note that while nothing should ever get hurt by
20attempting to reuse SSL session-IDs, there seem to be broken SSL
21implementations in the wild that may require you to disable this in order for
22you to succeed.

24Note that this is the negated option name documented. You can thus use
25--sessionid to enforce session-ID caching.
