Remarks

[C++] The pbstrUserID parameter contains valid data only if the method completes successfully.

The cookie data is always URL decoded.

This method is available when the MSCSAuthManager object is instantiated outside of the context of an ASP script.

This method is similar to the GetUserIDFromCookie method, but allows you to specify the encryption key. This enables the decryption of persistent cookies when the ticket encryption keys have changed. Retaining the user ID when replacing outdated cookies prevents the Business Analytics System from treating the returning user as a new user.

Example

' vUserID is a Variant.
' oAuthManager is a AuthManager object.

vUserID = oAuthManager.GetUserIDFromCookieAndKey(sCookieData, sKey)
