使用apache mod_mem_cache缓存Rest服务

Question

在Apache 2.2 httpd服务器后面，我有一个基于java rest的应用程序，具有这种服务:

GET /countries/canada

我想启用mod_mem_cache来加速这些服务:

CacheEnable mem /countries/*

可以使用通配符吗?
如果没有，有什么解决办法呢?

Answer 1

实际上，我们不需要通配符。

例如，如果a定义如下配置:

ProxyPass /jsontest/  http://echo.jsontest.com/
ProxyPassReverse /jsontest/  http://echo.jsontest.com/
<IfModule mod_cache.c>
    <IfModule mod_mem_cache.c>
        CacheEnable mem /jsontest/
        CacheDefaultExpire 300 
        MCacheSize 1024000 
        MCacheMaxObjectCount 10000 
        MCacheMinObjectSize 1 
        MCacheMaxObjectSize 2048000 
        CacheStorePrivate On
        CacheIgnoreNoLastMod On 
        CacheStoreNoStore On
        CacheIgnoreCacheControl On
    </IfModule>
</IfModule>

我可以请求:

http://localhost/jsontest/  

或

http://localhost/jsontest/titi/tutu  

和apache将存储每个响应并提供服务:

Incoming request is asking for an uncached version of /jsontest/, but we have been configured to ignore it and serve cached content anyway
mem_cache: Cached url: http://localhost:80/jsontest/?
Incoming request is asking for an uncached version of /jsontest/, but we have been configured to ignore it and serve cached content anyway
mod_cache.c(312): cache: serving /jsontest/
Incoming request is asking for an uncached version of /jsontest/titi/tutu, but we have been configured to ignore it and serve cached content anyway
mod_cache.c(753): cache: Caching url: /jsontest/titi/tutu
Incoming request is asking for an uncached version of /jsontest/titi/tutu, but we have been configured to ignore it and serve cached content anyway
mod_cache.c(312): cache: serving /jsontest/titi/tutu

小心:

与CacheStorePrivate, CacheIgnoreNoLastMod, CacheStoreNoStore和CacheIgnoreCacheControl，我禁用所有默认行为和强制缓存!
你得问问自己，这是不是你的要求。
