Question

给定示例的Apache2虚拟主机配置

<VirtualHost *:80>
    ServerName mywebsite
    DocumentRoot ${APACHE_DOCUMENT_ROOT}

    # This is because the hostname of the virtual-host serving the content is
    # used within the cache key. With the setting set to On virtual-hosts with
    # multiple server names or aliases will not produce differently cached
    # entities, and instead content will be cached as per the canonical
    # hostname.
    UseCanonicalName On

    # Cache content before mod_deflate
    CacheQuickHandler off
    SetOutputFilter CACHE
    AddOutputFilterByType DEFLATE application/json

    # X-Cache header will be added to response with the cache status
    CacheHeader on

    CacheSocache memcache:${MEMCACHED_URI}
    CacheSocacheMaxSize 983040
    CacheEnable socache /

    <Directory ${APACHE_DOCUMENT_ROOT}>
        FallbackResource /index.php
        AllowOverride None
    </Directory>
</VirtualHost>

在这种情况下，每当请求/products?lang=en时，都会使用/index.php?lang=en路径生成缓存键。这意味着/attributes?lang=en也将具有相同的缓存键。

以下是此特定情况的日志：

如何配置Apache2以生成具有实际请求路径的缓存键？

具有mod_dir的FallbackResource和正确的缓存键的Apache2 mod_cache配置
