[PATCH] Add RAM-only Proxy functionality - Bug Report #10592

[Xaver4all <xaver4all@gmx.de>]

[-- Attachment #1: Type: text/plain, Size: 1543 bytes --]

Squiddoesn't use RAM only for caching, if you set cachesize for disk
usage =0 andmemory cachesize >0 in GUI.
Now if you set "cache_size"=0 and "cache_mem">0,caching won't be
disabled completely ("cache deny all").
If you want todisable caching completely you must set "cache_size"=0 and
"cache_mem"=0.
Besides this "maximum_object_size_in_memory" will be set to 512KB.

Originally reported by qiller in Bugtracker form over one year. I just
created the diff an tested this on my IP-Fire.

Especially for the announced 64 Bit version of IP-Fire, where Squid can
handel more RAM, this may be useful.
