我在服务器配置和相关方面还是一个新手,但是我有一项任务是针对大量并发用户优化我们的服务,现在尝试设置适当的页面缓存。
site.com/target目录中有两个PHP页面,每个页面均应通过不同的规则进行缓存:
index.php。例如,将保存site.com/target? foo = 1 &qux = 2& bar = 3 ,两个site.com/target?foo=1 & bar = 3 和site.com/target? foo = 1 &baz = 100&qux = 5& bar = 3 将返回保存的副本,但具有至少一个具有不同值的目标参数的请求,例如site.com/target?foo=2 & bar = 3 将使其成为自己的缓存副本;
style.php应该在考虑整体查询字符串的情况下进行缓存,site.com / target?foo = 1和site.com/target?foo=2都将自己的副本保存在缓存中。
所有其他PHP文件应保持不变。目前没有任何登录/身份验证,因此,它不应对Cookie做出反应。 site.com的public_html主目录已安装WordPress,但整个目标文件夹均未引用它。
到目前为止,这是我的配置,在服务器指令中的位置指令中定义了这两个规则:

当然,这似乎不起作用–指示页面的负载测试仍然显示出请求数量和响应时间之间的直接依赖关系,就像根本没有缓存一样。
我想知道我的配置出了什么问题,如果可能的话,我想知道我的配置可以正常工作。请让我知道是否可以详细介绍我们的服务器配置。预先感谢!
