What does the acl typeofclient1 look like?

Lots of good info, but what OS? What kernel?

Why do you do this?

This might be effected by the headers returned with the object. Using
"no_cache allow all" is not recommended with the default
refresh_pattern, due to the likelihood of caching dynamically generated
content.

Perhaps it's related to the malloc libraries you are using... The only
information I could find about libgnumalloc indicates that it's pretty
outdated, which indicates that the underlying OS is... Aging.

I don't know of any reason not to. But for limiting bandwidth,
delay_pools might be a better choice.

Update your Squid version, and perhaps your OS.
