Configuring object-type detection

The Default catch-all object-type detection policy covers the most typical use cases, but you might find situations in which you need to either alter its default rules or create a new policy. For example:

• Your web application processes a specific file type that is not yet detected.
• You need the system to treat XML files as documents only when they are downloaded from your web application by unregistered users.

Because these exceptional issues are not handled by the default rules, you must either alter the existing rules or create a new object-type detection policy.

Object-type detection policy is a prioritized list of object-type detection rules that apply to an object when a certain condition is true.

To create an object-type detection policy

1. On the Administration page of a

   , click Object type detection.
2. On the Action menu, click Add.

4. In the Expression field, define a condition that must be satisfied for the policy to execute.
    Use the Expression Builder to help you provide the most precise query.
5. Click Save.
    You have provided the condition, and now you must fill this policy with rules for object-type detection.
6. In the object-type detection policy that you have created, click Add object type detection rule.
7. Select an object type.
8. In the Expression box, specify a filter expression to identify which objects are comprised by this object type.
9. Click Save.
10. Repeat from step 6 to define all the types.
    
    Objects that are not defined by this policy are processed by the Default catch-all policy.
