NAME

6       CURLOPT_SSL_SESSIONID_CACHE - use the SSL session-ID cache
7

SYNOPSIS

9       #include <curl/curl.h>

11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_SESSIONID_CACHE,
12                                long enabled);
13

DESCRIPTION

15       Pass  a  long  set  to  0  to  disable  libcurl's use of SSL session-ID
16       caching. Set this to 1 to enable it. By default all transfers are  done
17       using the cache enabled. While nothing ever should get hurt by attempt‐
18       ing to reuse SSL session-IDs, there seem to be or have been broken  SSL
19       implementations in the wild that may require you to disable this in or‐
20       der for you to succeed.
