我在 debian 上运行 apache 2.2.22。
我尝试在此服务器上启用放气，但无论我做什么，响应都不会放气。
以下是已启用模块的列表：
apache2ctl -M

如果我现在尝试从该站点获取一个简单的 html 文件，它不会被压缩。php输出也会发生同样的情况：
curl --compressed -I http://www.tren.at/test.html
HTTP/1.1 200 OK

我已经在 php.ini 中禁用了 output_buffering 和 zlib.output_compression。
我的配置中某处有错误吗？我还能尝试什么来查找问题/解决问题？
编辑：
有趣的是，当我在配置中出现语法错误时，我得到的 500 错误被压缩了！
