.TH CURLOPT_SSL_SESSIONID_CACHE 3 "19 Jun 2014" libcurl libcurl
|
|
.SH NAME
|
|
CURLOPT_SSL_SESSIONID_CACHE \- use 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
|
|
