If the file name points to an 21existing alt-svc cache file, that gets used. After a completed transfer, the 22cache is saved to the file name again if it has been modified. 23 24Specify a "" file name (zero length) to avoid loading/saving and make curl 25just handle the cache in memory. 26 27If this option is used several times, curl loads contents from all the 28files but the last one is used for saving. 29
