NAME

       CURLOPT_SSL_SESSIONID_CACHE - use the SSL session-ID cache

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

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

DEFAULT

       1

PROTOCOLS

       All TLS-based

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         /* switch off session-id use! */
         curl_easy_setopt(curl, CURLOPT_SSL_SESSIONID_CACHE, 0L);
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
