StringNotLike

StringNotLike compares a string in a request to a list of strings in your policy. The policy values can include asterisks (*) to match multiple characters and question marks (?) to match a single character. The comparision is case sensitive.

To match a request, the context key can be absent, but if present it must NOT match any of the strings in your policy.

You can use policy variables in the value of this operator.
