Why doesn't the ProxySG return an ICAP exception page when a virus is detected in a large file if trickling is enabled


<< Back to Knowledge Search

Solution

Overview

This is expected behavior. For trickling to start, the ProxySG has to send an HTTP/200 response back to the client. If a virus is detected during data trickling, the proxy can't send another HTTP/200 with the exception page so the data transfer simply stops.

If the exception page is absolutely necessary, trickling needs to be disabled so that the proxy can use it's HTTP/200 response to serve the exception page.
