.SH 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 \fIbitmask\fP with the correct set of features to instruct
|
|
libcurl how to handle HSTS for the transfers using this handle.
|
|
.SH BITS
|
|
.IP CURLHSTS_ENABLE
|
|
Enable the in\-memory HSTS cache for this handle.
|
|
.IP CURLHSTS_READONLYFILE
|
|
Make the HSTS file (if specified) read\-only \- makes libcurl not save the cache
|
|
to the file when closing the handle.
|
|
.SH DEFAULT
|
|
0. HSTS is disabled by default.
|
|
.SH PROTOCOLS
|
|
HTTPS and HTTP
