.SH NAME
|
|
CURLOPT_CA_CACHE_TIMEOUT \- life\-time for cached certificate stores
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CA_CACHE_TIMEOUT, long age);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a long, this sets the timeout in seconds. This tells libcurl the maximum
|
|
time any cached certificate store it has in memory may be kept and reused for
|
|
new connections. Once the timeout has expired, a subsequent fetch requiring a
|
|
certificate has to reload it.
|
|
|
|
Building a certificate store from a \fICURLOPT_CAINFO(3)\fP file is a slow
|
|
operation so curl may cache the generated certificate store internally to speed
|
|
up future connections.
|
|
|
|
Set to zero to completely disable caching, or set to \-1 to retain the cached
|
|
store remain forever. By default, libcurl caches this info for 24 hours.
|
|
.SH DEFAULT
|
|
86400 (24 hours)
