Hypertext Transfer Protocol 2 (HTTP2) is an application-level protocol for distributed, collaborative, hypermedia information systems. This test suite can be used to test HTTP2 Server implementations for security flaws and robustness problems. HTTP2 is successor of HTTP. HTTP2 has similar headers like in HTTP/1.1 but headers have binary packing and values can be Huffman encoded. Biggest changes in HTTP2 compared to HTTP/1.1 is that protocol is binary instead of ASCII and supports multiple streams.
