Good hint, thanks! If we did have such a control, what is the wired
memory that squid will use for each entry? In an email earlier I
wrote...

 - Each index entry takes between 56 bytes and 88 bytes, plus
additional, unspecificed overhead. Is 1KB per entry a reasonable
conservative estimate?

 - Discussions about compressing or hashing the URL in the index are
recurrent - is the uncompressed URL there? That means up to 4KB per
index entry?

the notes I read about the index structure were rather old...
