Kerio Control 8.4.0 and higher includes a full HTTPSHypertext Transfer Protocol - version of HTTP secured by SSL. filter. Read more in the Filtering HTTPS connections article. However, if you do not want to use the full HTTPS filter, be aware of the following facts:
- HTTPS filtering of URLs is limited only to the domain name. The resource identifier part of the request (e.g. /path/index) is not considered as part of the condition of a rule unless non-transparent proxy server is used.
- It is not possible to filter individual objects at HTTPS servers.
- For technical reasons, it is not possible to apply HTTPS blocking to clients using Internet Explorer on Windows XP.
