This option enables HSTS for the transfer. If the file name points to an
existing HSTS cache file, that will be used. After a completed transfer, the
cache will be saved to the file name again if it has been modified.

If curl is told to use HTTP:// for a transfer involving a host name that
exists in the HSTS cache, it upgrades the transfer to use HTTPS. Each HSTS
cache entry has an individual life time after which the upgrade is no longer
performed.

Specify a "" file name (zero length) to avoid loading/saving and make curl
just handle HSTS in memory.

If this option is used several times, curl will load contents from all the
files but the last one will be used for saving.
copyright: update all copyright lines and remove year ranges - they are mostly pointless in all major jurisdictions - many big corporations and projects already don't use them - saves us from pointless churn - git keeps history for us - the year range is kept in COPYING checksrc is updated to allow non-year using copyright statements Closes #10205 2023-01-02 15:51:48 +03:00			`c: Copyright (C) Daniel Stenberg, <daniel@haxx.se>, et al.`
docs/cmdline-opts: add copyright and license identifier to each file gen.pl now insists on C: and SPDX-License-Identifier: fields to be present in all files. Closes #9002 2022-06-14 01:12:03 +03:00			`SPDX-License-Identifier: curl`

curl.1: provide examples for each option The file format for each option now features a "Example:" header that can provide one or more examples that get rendered appropriately in the output. All options MUST have at least one example or gen.pl complains at build-time. This fix also does a few other minor format and consistency cleanups. Closes #7654 2021-08-31 17:37:14 +03:00			`Example: --hsts cache.txt $URL`
curl.1: require "see also" for every documented option gen.pl now generates a warning if the "See Also" field is not filled in for a command line option All command line options now provide one or more related options. 167 "See alsos" added! Closes #8019 2021-11-15 17:58:20 +03:00			`See-also: proto`
cmdline/docs: add a required 'multi' keyword for each option The keyword specifies how option works when specified multiple times: - single: the last provided value replaces the earlier ones - append: it supports being provided multiple times - boolean: on/off values - mutex: flag-like option that disable anoter flag The 'gen.pl' script then outputs the proper and unified language for each option's multi-use behavior in the generated man page. The multi: header is requires in each .d file and will cause build error if missing or set to an unknown value. Closes #9759 2022-10-18 11:39:43 +03:00			`Multi: append`
