Apache cache on Windows

jebat_ks

Let me start by saying that I'm not familiar with Apache(or Windows). But let just say that I have no choice

Currently trying to setup mod_cache & mod_mem_cache, as Apache on my server utilized CPU like crazy but have loads of unused memory space.

I've enabled

LoadModule mem_cache_module modules/mod_mem_cache.so
LoadModule cache_module modules/mod_cache.so

in httpd.conf

But what baffles me is where below config should go? httpd.conf or httpd-vhosts.conf?

<IfModule mod_mem_cache.c>
    CacheEnable mem C:/webroot
    MCacheSize 6144
    MCacheMaxObjectCount 1000
    MCacheMinObjectSize 1
    MCacheMaxObjectSize 2048
</IfModule>

I've actually tried both, restart Apache and didn't see anything loaded to memory even after few hour. I have few hundreds of visitor/min so it shouldn't be the case. Even better, there nothing weird in log.

My vhost.
I want to setup the cache on everything inside 135.example.com only

I swear I've googled every possible keyword that I can think of, but no appropriate result for example of mod_cache config on Windows yet . Would like to hear your input on this.
