Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# NAME
|
|
|
|
CURLOPT_SSL_SESSIONID_CACHE - use the SSL session-ID cache
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
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);
|
|
}
|
|
}
