Method Detail

compareToken

public void compareToken(String passedToken)

Description copied from interface: StaleStateProtectionService

Compare the state version token provided by the request to what is resident in the user session. If the tokens are not equal, the determination is made that the request is coming from a stale page and a StaleStateServiceException is emitted.

Specified by:

compareToken in interface StaleStateProtectionService

Parameters:

passedToken - the state version token from the request

getStateVersionToken

public String getStateVersionToken()

Description copied from interface: StaleStateProtectionService

Retrieve the state version token resident in the user's session, or create one if it doesn't exist.

Specified by:

getStateVersionToken in interface StaleStateProtectionService

Returns:

invalidateState

public void invalidateState()

Description copied from interface: StaleStateProtectionService

Remove the current state version token in the user's session, if exists. This usually occurs in response to a key state change.

Specified by:

invalidateState in interface StaleStateProtectionService

invalidateState

public void invalidateState(boolean notify)

Description copied from interface: StaleStateProtectionService

Remove the current state version token in the user's session, if exists. This usually occurs in response to a key state change.

Specified by:

invalidateState in interface StaleStateProtectionService

Parameters:

notify - Whether or not the request should be notified that state was invalidated. See StaleStateProtectionService.sendRedirectOnStateChange(HttpServletResponse, String...).

sendRedirectOnStateChange

public boolean sendRedirectOnStateChange(javax.servlet.http.HttpServletResponse response,
                                         String... stateChangeParams)
                                  throws IOException

Description copied from interface: StaleStateProtectionService

Utility method to send a redirect for the current url with state change params cleared. State change params are request url parameters that drive primary context change. For example, url parameters for sandbox, catalog and profile changes are considered state change params. When such a param is utilized, the state token is reset to represent the fundamental context change and is stored in session. However, it is now desirable to redirect the user to the target url without the state change params to avoid a subsequent check.

Specified by:

sendRedirectOnStateChange in interface StaleStateProtectionService

Parameters:

response - the current http response

stateChangeParams - any request parameter names being used by the system to drive state change

Returns:

whether or not a redirect was sent based on detection of an earlier call to StaleStateProtectionService.invalidateState()

Throws:

IOException

isEnabled

public boolean isEnabled()

Description copied from interface: StaleStateProtectionService

Whether or not the protection provided by this service is active.

Specified by:

isEnabled in interface StaleStateProtectionService

Returns:

getStateVersionTokenParameter

public String getStateVersionTokenParameter()

Description copied from interface: StaleStateProtectionService

Retrieve the parameter key used to harvest the state version token value from the request

Specified by:

getStateVersionTokenParameter in interface StaleStateProtectionService

Returns:
