Chained ICAP Anti Virus Server
If eCAP antivirus adapter is not applicable (for example in case of FreeBSD 11), it is also possible to chain any third party ICAP antivirus server with Web Safety. Web UI has support of minimal ICAP chain configuration (enable/disable) built in.
The following screenshot illustrates the configuration.
We will give examples of ICAP chaining using two third party ICAP servers.
Please note there were reports of some random inconsistencies on some sites that result into ICAP errors when using both Web Safety and ICAP Antivirus engine in an ICAP chain. Unfortunately the reason for this is still unknown. Currently recommended solution for this problem is to exclude such sites from ICAP filtering.
