They are needed if you want to take advantage of the core HTTP/2 features. Otherwise you can slightly benefit from the compressed HTTP headers but you are not using the HTTP/2 pipelining/multiplexing. I would suggest to have a look at the http2-download.c example: https://github.com/curl/curl/blob/curl-7_53_0/docs/examples/http2-download.c Kamil _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
