CURLOPT_SSL_SESSIONID_CACHE3
Use the ssl session-id cache
Usage
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_SESSIONID_CACHE,
long enabled);
Overview
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
Examples
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
/* switch off session-id use! */
curl_easy_setopt(curl, CURLOPT_SSL_SESSIONID_CACHE, 0L);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
Return value
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
