# `--hsts`

|
|
Enable HSTS for the transfer. If the filename points to an existing HSTS cache
|
|
file, that is used. After a completed transfer, the cache is saved to the
|
|
filename again if it has been modified.
|
|
|
|
If curl is told to use HTTP:// for a transfer involving a hostname 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 "" filename (zero length) to avoid loading/saving and make curl just
|
|
handle HSTS in memory.
|
|
|
|
If this option is used several times, curl loads contents from all the
|
|
files but the last one is used for saving.
