| .TH CURLOPT_SSL_SESSIONID_CACHE 3 "November 04, 2020" "libcurl 7.78.0" "curl_easy_setopt options" |
| |
| .SH NAME |
| CURLOPT_SSL_SESSIONID_CACHE \- enable/disable use of the SSL session-ID cache |
| .SH SYNOPSIS |
| .nf |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_SESSIONID_CACHE, |
| long enabled); |
| .SH 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. |
| .SH DEFAULT |
| 1 |
| .SH PROTOCOLS |
| All TLS-based |
| .SH EXAMPLE |
| .nf |
| 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); |
| } |
| .fi |
