# `--alt-svc`
This option enables the alt-svc parser in curl. If the filename points to an
existing alt-svc cache file, that gets used. After a completed transfer, the
cache is saved to the filename again if it has been modified.
Specify a "" filename (zero length) to avoid loading/saving and make curl just
handle the cache in memory.
If this option is used several times, curl loads contents from all the
files but the last one is used for saving.
