The FwpsQueryConnectionRedirectState0 function returns the connection redirect state.
Note FwpsQueryConnectionRedirectState0 is a specific version of FwpsQueryConnectionRedirectState. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.
redirectRecordsThe redirect records handle indicated to ALE_CONNECT_REDIRECT callout by the classify metadata.
redirectHandleA redirect handle that was previously created by a call to the FwpsRedirectHandleCreate0 function.
redirectContextAn optional handle to the redirect context. If the pointer is specified, and if the connection redirect state FWPS_CONNECTION_REDIRECT_STATE associated with the injection handle is FWPS_CONNECTION_REDIRECTED_BY_SELF or FWPS_CONNECTION_PREVIOUSLY_REDIRECTED_BY_SELF, the redirect context supplied when the connection was redirected will be returned.
The FwpsQueryConnectionRedirectState0 function returns one of the states that are specified in the FWPS_CONNECTION_REDIRECT_STATE enumeration.
A callout driver calls the FwpsQueryConnectionRedirectState0 function to get the redirect state of a connection.
If the redirect status is FWPS_CONNECTION_NOT_REDIRECTED, the ALE_CONNECT_REDIRECT callout can proceed to proxy the connection.
If the redirect status is FWPS_CONNECTION_REDIRECTED_BY_SELF, the ALE_CONNECT_REDIRECT callout should return FWP_ACTION_PERMIT/FWP_ACTION_CONTINUE.
If the redirect status is FWPS_CONNECTION_REDIRECTED_BY_OTHER, the ALE_CONNECT_REDIRECT callout could proceed to proxy the connection if it does not trust the other inspector's result.
If the redirect status is FWPS_CONNECTION_PREVIOUSLY_REDIRECTED_BY_SELF, the ALE_CONNECT_REDIRECT callout must not perform redirection even if other inspectors' results are not acceptable. In this case, it must either permit or block the connection (at the ALE_AUTH_CONNECT layer).
