MBS( "CURL.SetOptionSSLSessionIDCache"; curl; Value )   More


Parameter Description Example
curl The CURL session handle. $curl
Value Whether to cache session IDs. 1


Returns "OK" on success.


Controls SSL session-ID caching.
Set to 0 to disable cache. Set this to 1 to enable it. By default all transfers are done using the cache. While nothing ever should get hurt by attempting to reuse SSL session-IDs, there seem to be broken SSL implementations in the wild that may require you to disable this in order for you to succeed.
