Synopsis

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

Description

curl_easy_setopt options                        CURLOPT_SSL_SESSIONID_CACHE(3)



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 nothing ever should get hurt by attempt-
       ing  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
       Added in 7.16.0

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