NAME

6       CURLOPT_SSL_SESSIONID_CACHE  - enable/disable use of the SSL session-ID
7       cache
8

SYNOPSIS

10       #include <curl/curl.h>
11
12       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_SESSIONID_CACHE,
13                                long enabled);
14

DESCRIPTION

16       Pass a long set to  0  to  disable  libcurl's  use  of  SSL  session-ID
17       caching.  Set this to 1 to enable it. By default all transfers are done
18       using the cache enabled. While nothing ever should get hurt by attemptā€
19       ing  to reuse SSL session-IDs, there seem to be or have been broken SSL
20       implementations in the wild that may require you  to  disable  this  in
21       order for you to succeed.
