| 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. |
