Chapter 12      Outbound Malware Scanning
Evaluating Outbound Malware Scanning Policy Group Membership
The Web Proxy reads sequentially through each policy group in the policies table. It compares the upload 
request status to the membership criteria of the first policy group. If they match, the Web Proxy applies 
the policy settings of that policy group.
If they do not match, the Web Proxy compares the upload request to the next policy group. It continues 
this process until it matches the upload request to a user defined policy group. If it does not match a user 
defined policy group, it matches the global policy group. When the Web Proxy matches the upload 
request to a policy group or the global policy group, it applies the policy settings of that policy group.
Matching Client Requests to Outbound Malware Scanning Policy Groups
 shows how the Web Proxy evaluates an upload request against the Outbound 
Malware Scanning groups.
