As suggested by Oliver "giller" Fieker <oli(a)new-lan.de>
in bug 10592 I added the functionality to use the squid as ram-only cache.

Further it defines the maximum_object_size_in_memory
as 2% of the in the webif defined "Memory cache size".
The maximum_object_size_in_memory should have a useful
size of the defined memory cache and I don't want to
create another variable which muste be fulled in by the user.
