NAME

     CURLOPT_SSL_SESSIONID_CACHE - enable/disable use of 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  noth-
     ing  ever  should  get  hurt  by  attempting  to  reuse  SSL
     session-IDs, there seem to be or have been broken SSL imple-
     mentations  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

     Added in 7.16.0

RETURN VALUE

     Returns  CURLE_OK  if   the   option   is   supported,   and
     CURLE_UNKNOWN_OPTION if not.
