为什么 nginx gzip_http_version 默认为 HTTP 1.1

Question

gzip_http_versionnginx 的 gzip 模块中设置的默认值为HTTP 1.1。为什么？使用 gzip 和 HTTP 1.0 有什么问题吗？

Answer 1

nginx gzip_http_version 可以有 HTTP 1.0 并且有它的警告。

When HTTP version 1.0 is used, the Vary: Accept-Encoding header is not set. As
this can lead to proxy cache corruption, consider adding it with add_header.
Also note that the Content-Length header is not set when using either version.
Keepalives will therefore be impossible with version 1.0, while for 1.1 it is
handled by chunked transfers.
