I don't have any options neither in config nor in source files nor in cachemgr config output for shortcircuit. Squid is 3.1.0.15 Thank you for this great tip. That is exactly the problem I am facing (I can assure you taht I did not have this problem with older squids as far as I recall). I will try with a newer version and see if the issue is reproducible or was a bug. Rest of your comments are appreciated Amos. As always, I pay great attention to them.
