Hi Alex With your explanation, I was able to reproduce the behaviour: -> I opened a website within the browser -> Before the site was loaded completely, I closed the browser -> This causes squid to close the current icap-transaction (as you described) (-> ABORT-entries in the access.log) -> In the icap-log, I have the icap-error mentioned in my first post. So, this behaviour makes now sense. Probably the icap-daemon (third-party software) could be advised, not to throw an error but rather an informational message. Thanks a lot for your help and hints.
