When you build curl, you have the option to build it with HTTP\/3 support<\/a> enabled. The HTTP\/3 support in curl is still considered experimental so it is still not enabled by default.<\/p>\n\n\n\n

The HTTP\/3 support in curl depends on the presence and support from third party libraries. You need to select and enable a specific HTTP\/3 backend when you build curl.
