StringEqualsIgnoreCaseIfExists

StringEqualsIgnoreCaseIfExists

StringEqualsIgnoreCaseIfExists compares a string in a request to a list of strings in your policy. The comparison is case insensitive.

To match a request, the context key can be absent, but if present it must match at least one of the strings in your policy.

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