Cache digests

Hi, i want some information about the cache digests version of Squid.

1) maybe i missed something, but where can i change the frequency of
requests for peer cache digests. Is it hard coded ? what is it by
default ?

2) can anyone point to me where i can find the amount of memory used by
a digest (disk and memory) ? (i know it should be in cachemgr.cgi)

Thanx,
        Christian
