	VARIANT_BOOL* pfBlock
);

Parameters

pfBlock: Pointer to a Boolean variable that is set on return to VARIANT_TRUE if requests with an invalid UTF8-encoded URL will be blocked, or to VARIANT_FALSE if requests with an invalid UTF8-encoded URL will not be blocked.
fBlock: Boolean value that indicates whether requests with an invalid UTF8-encoded URL will be blocked.

[Visual Basic]

Property BlockInvalidUtf8Urls As Boolean

Property Value

Boolean value that indicates whether requests with an invalid UTF8-encoded URL will be blocked.

Remarks

This property is read/write. Its default value is False (VARIANT_FALSE in C++).

When this property is set to True (VARIANT_TRUE in C++), Forefront TMG verifies the validity of the URL in each request, assuming that the URL is encoded in UTF8 format, and blocks a request if the URL is found to be invalid. URLs that contain international characters and are not encoded in UTF8 format will be considered invalid. Nevertheless, as a best security practice, we recommend that you change the value of this property to True (VARIANT_TRUE in C++).
