Session Timeout

[Guest]

Message from: "Harry Rogers"

 

Hi Farshad

 

Is it possible to publish and 'OnTimeOut' event ?

 

What I am trying to implement is a mechanism where after a period of no

user activity a password is once again required from the user to

continue.

 

The application I am developing will replace an older desktop one that

has a nice feature in that it 'decays' back to a secure position after

a given time interval of no user input.

I could get this effect by having every user event pass through a timer

but that makes for a lot of work and the server module is already

noting when a user event occurs so that would seem a sensible place to

grab that notification from.

 

something like

 

procedure TUniServerModule.UniGUIServerModuleOnTimeOut(var NewTimeOut :

integer);

 

popping a zero into NewTimeout allows the timeout to complete and a

nonzero positive integer causes the timeout to assume that new value.

 

 

Best regards

Seems like a nice feature.Logged as #855 for implementation.

 

However, you can't send anything to the client in this event. For example,

you can't pop up a login dialog upon timeout because you can't push anything

to the client if there is no request from it first.

 

To do this you must implement a timer which will poll the server frequently.

That's fine - I would simply set a value server side in this instance.

 

Thanks again
