Apache as a proxy/cache

[ukgrahams]

I have set up apache on a Win 98 machine as a caching proxy, hoping to speed up access to sites by storing them locally. ( I have a 128k ISDN which for a school with over 100 PCs is hopelessly slow!)

I have successfully set up the proxy module which also accesses a remote proxy for filtering, however when more than 4 or 5 users access the same site there is no increase in access speed at all, as though the cache was not there. Could somebody check my conf file entries below and let me know if there is something I am doing wrong

Thanks

Why arent you loading the disk_cache_module ? you appear to have it commented out, you are loading the mem_cache_module further up in the config so thats ok to be commented here!

Try that for a start ..... Good Luck Laurie.

<IfModule mod_cache.c>
#LoadModule disk_cache_module modules/mod_disk_cache.so
<IfModule mod_disk_cache.c>
CacheRoot &quot;C:/Program Files/Apache Group/Apache2/proxy&quot;
CacheSize 10000000000
CacheEnable disk /
CacheDirLevels 5
CacheDirLength 2
</IfModule>

#LoadModule mem_cache_module modules/mod_mem_cache.so
<IfModule mod_mem_cache.c>
CacheEnable mem /
MCacheSize 128000
MCacheMaxObjectCount 100
MCacheMinObjectSize 1
MCacheMaxObjectSize 2048
</IfModule>
</IfModule>

</IfModule>

The disk cache module is only commented out in the proxy section - it is enabled higher up in the Load Module section.

Thanks anyway
