![Apache - 已启用 http/2,但仍在请求中提供 http/1.1](https://linux22.com/image/784642/Apache%20-%20%E5%B7%B2%E5%90%AF%E7%94%A8%20http%2F2%EF%BC%8C%E4%BD%86%E4%BB%8D%E5%9C%A8%E8%AF%B7%E6%B1%82%E4%B8%AD%E6%8F%90%E4%BE%9B%20http%2F1.1.png)
Apache/2.4.34 (Red Hat) OpenSSL/1.0.2k-fips 在 CentOS 7、PHP 7.4.33 上,我已按照以下指南安装并启用了 http/2如何从 Centos 包/yum 启用 http/2?。没有报告任何错误并且模块已加载但页面仍然通过 http/1.1 提供服务。
我已经从 prefork mpm 转移到 event,所以这不是问题。
这不是浏览器缓存问题。
Apache 已重新启动多次。
