Subject Re: [users@httpd] Caching files on reverse proxy
Date Wed, 11 Nov 2009 01:10:11 GMT
Hi Brian,

I have set up Apache with mod_proxy with following config
__________________

<IfModule mod_cache.c>
<IfModule mod_disk_cache.c>
CacheRoot d:/apache_cache
CacheEnable disk /
CacheDirLevels 2
CacheDirLength 3
</IfModule>
__________________

.data and .header files are stored in cache. Is it possible to retrieve the
cached files on Apache?

Thanks in advance.
