So if I understand this right ,
1. There is no sessionid reuse when I invoke "curl -k https://URL-PATH " twice ( separate invocations ).

2. When I invoke curl -k https://URL-PATH curl -k https://URL-PATH curl -k https://URL-PATH , all three requests happen within the same TCP connection and so the question of sessionid reuse does not arise.

In which case , when would I use the -no-sessionid flag ? What purpose exactly does this flag serve ?
