# NAME
|
|
|
|
CURLOPT_HSTS_CTRL - control HSTS behavior
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
#define CURLHSTS_ENABLE (1L << 0)
|
|
#define CURLHSTS_READONLYFILE (1L << 1)
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTS_CTRL, long bitmask);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
HSTS (HTTP Strict Transport Security) means that an HTTPS server can instruct
|
|
the client to not contact it again over clear-text HTTP for a certain period
|
|
into the future. libcurl then automatically redirects HTTP attempts to such
|
|
hosts to instead use HTTPS. This is done by libcurl retaining this knowledge
|
|
in an in-memory cache.
|
|
|
|
Populate the long *bitmask* with the correct set of features to instruct
|
|
libcurl how to handle HSTS for the transfers using this handle.
|
|
|
|
# BITS
|
|
|
|
## CURLHSTS_ENABLE
|
|
|
|
Enable the in-memory HSTS cache for this handle.
|
|
|
|
## CURLHSTS_READONLYFILE
|
|
|
|
Make the HSTS file (if specified) read-only - makes libcurl not save the cache
|
|
to the file when closing the handle.
