Media type filtering
Change a property in a media type filtering rule
To let a media type filtering rule filter a different kind of media types, you can, for example, replace the
MediaType.EnsuredTypes property in the rule criteria with MediaType.NotEnsuredType.
To replace this property:
1 Go to Policy | Rule Sets.
2 On the rule sets tree, select a rule set for media type filtering, for example, the nested Download
Media Type rule set in the Media Type Filtering rule set.
3 Select a rule, for example, Block types from Download Media Type Blocklist, and click Edit. The
Edit Rule window opens.
4 Select Rule Criteria and under Criteria select the rule. Then click Edit. The Edit Criteria window
opens.
5 From the drop-down list under Property select a new property, for example,
MediaType.NotEnsuredTypes (instead of MediaType.EnsuredTypes).
6 From the list under Parameter – Value, select Not Ensured Download Media Type Blocklist.
7 Click OK and then Finish to close the windows. The modified rule appears on the settings pane.
8 Click Save Changes.
The modified rule blocks not ensured media types that are on your new list.
If you want to keep the old rule to have rules for both filtering ensured and not ensured media types,
use the Copy and Paste buttons above the list of rules to copy the old rule and apply your modifications
to the copied rule.
The Move up and Move down buttons allow you to move the additional rule to the appropriate position,
which should be immediately before or after the old rule.
